Hollywood’s hottest commodity? An AARP card.

Victor Hugo once said, “Forty is the old age of youth; fifty the youth of old age.” Others have claimed that “Fifty is the new 30,” “You’re only as old as you feel” and “Men look more distinguished as they age.”

Regardless of whatever age-related cliché you can think of, men in their 50s are having a moment in pop culture. Nowhere is this more evident than in Fox’s back-to-back Tuesday night scheduling of two buzzy new shows starring robust, handsome, seemingly ageless men who are on the back side of a century: Grandfathered, featuring a 52-year-old John Stamos, and The Grinder, featuring Rob Lowe, who’s 50.

Let’s take a closer look at some silver foxes who were Hollywood heartthrobs in their early years but have re-emerged in the prime (time) of their lives on stage and screen. Warning: If you remember these guys as your Hollywood crushes 20 or 30 years ago, you’re going to feel very, very old.

Lenny Kravitz (51)

Looking at least a decade younger than his birth certificate would indicate, Lenny Kravitz is a singer, songwriter, actor (Precious, The Hunger Games), producer, clothing designer and multi-instrumentalist.

As you can probably tell by his retro-chic hair and wardrobe, he’s also a cool dude.

The rocker made headlines this summer when, at a concert in Stockholm, he had the worst kind of wardrobe malfunction a guy could have. It involved ripped pants and a revelation that showed he was, um, “in commando.” (He calmly left the stage, changed pants, apologized to the crowd and continued the frenetic show, belting out tunes from his latest release, 2014’s Strut.)

Winner of the Grammy Award for best male rock vocal performance a record-breaking four years in a row (1999-2002), Kravitz is probably best known for 1993’s Are You Gonna Go My Way from the album of the same name. His first album was 1989’s Let Love Rule, which he recorded while married to actress Lisa Bonet (of the ’80s hit The Cosby Show).

Brad Pitt (51)

A two-time winner of People magazine’s “Sexiest Man Alive” (a feat shared by Johnny Depp and George Clooney), Brad Pitt is much more than the pretty face moviegoers were introduced to in Thelma and Louise (1991) and Cool World (1992).

He’s also a high-profile producer (World War Z, 12 Years a Slave) and one of Hollywood’s most sought-after actors, playing pivotal roles in such diverse films as the quietly beautiful A River Runs Through It (1992), the cult favorite Fight Club (1999) and the oddly charming Inglourious Basterds (2009), a World War II revenge fantasy where Pitt gloriously states: “You probably heard we ain’t in the prisoner-takin’ business; we in the killin’ Nazi business. And cousin, business is a-boomin’.”

His first speaking role on TV was in the soap Another World (1987), where he played Chris, a high school basketball player.

But let’s talk about what he’s really best known for: His hall-of-fame place in American tabloids, alongside his wife, Angelina Jolie (and, for that matter, ex-wife Jennifer Aniston). On Nov. 13, the eternally youthful Pitt will star alongside Jolie in By the Sea, their first feature film collaboration since 2005’s Mr. & Mrs. Smith.

John Stamos (52)

Say the name John Stamos, and most people will immediately think of Jesse Katsopolis, the lovable, mullet-coiffed hunk-rocker he played on the kid-friendly ABC sitcom Full House (1987-1995) who made the phrase “Have mercy” famous.

However, Stamos has had much more than a one-dimensional career, as evidenced by roles (some recurring) on such popular shows as Friends, ER and Glee. And his first major acting debut was on the daytime soap General Hospital (1982-1984), in which he played foster child Blackie Parrish.

His latest star turn is in the new Fox sitcom Grandfathered, in which he plays Jimmy Martino, a bachelor who discovers that he has a child and a grandchild. Critic Merrill Barr of Forbes called the debut episode “sweet and endearing.”

Next year, Stamos will return to his Uncle Jesse role in the highly anticipated Full House sequel, Fuller House, a Netflix original series.

He also stars as himself — and pokes fun at himself a bit — in Oikos Greek yogurt commercials.

Robert Downey Jr. (50)

While he may not make a habit out of screaming “I am Iron Man” the way Black Sabbath frontman Ozzy Osbourne does in concert, Robert Downey Jr. might as well adopt a similar battle cry.

In the three “Iron Man” films and in both “Avengers” movies, Downey Jr. portrays Marvel Comics’ Tony Stark and his armor-wearing alter ego to utter perfection, nailing the former’s brash cockiness and the latter’s unbridled heroism as no other actor could.

His first film was 1970’s Pound, which was written and directed by his father, Robert Downey Sr.

From 1996 through 2001, the former Brat Packer battled drug addiction and was arrested several times for possession, but he’s now the poster child for the Hollywood comeback career, raking in hundreds of millions of dollars for the aforementioned blockbusters (with more to follow) and turning in fine performances in such films as Good Night, and Good Luck (2005), Tropic Thunder (2008) and The Judge (2014).

Rob Lowe (51)

Rob Lowe, who credits his boyish good looks to a skin-care product line he endorses, got his big break in The Outsiders (1983), a Brat Pack movie released several years before the term was even coined.

In 1986, he won a “Razzie” for worst supporting actor in St. Elmo’s Fire (1985), a key Brat Pack film. After enduring a humiliating sex-tape scandal in 1988, he rebounded nicely with a comedic turn in Wayne’s World (1992), followed by roles in such funny films as Tommy Boy (1995) and the “Austin Powers” trilogy.

TV viewers know Lowe as Sam Seaborn in The West Wing, Chris Traeger in Parks and Recreation and, currently, Dean Sanderson Jr. in The Grinder, which USA Today called “buoyant, legal fun” and “an amiable show-business spoof.”

Lowe further endears himself to fans for his 25-plus years of sobriety (he was pretty wild during his Brat Pack years, as revealed in his 2011 autobiography, Stories I Only Tell My Friends), and his steadfast devotion to his wife, whom he married in 1991.

First time to play the president of the United States? 2013’s Killing Kennedy, a made-for-TV movie based on Bill O’Reilly’s bestselling book.

Johnny Depp (52)

Known for playing such quirky characters as Edward Scissorhands (1990), Ed Wood (1994) and Willy Wonka (2005, Charlie and the Chocolate Factory), Johnny Depp is one of the most versatile actors in Hollywood — a modern “Man of a Thousand Faces,” if you will — unafraid to obscure his leading-man good looks with heavy makeup (see 2013’s The Lone Ranger, among others), wild hair styles and goofy facial contortions.

He’s virtually unrecognizable as gangster James “Whitey” Bulger in Black Mass, which hit theaters Sept. 18.

He crept eerily onto the Hollywood scene in 1984’s A Nightmare on Elm Street, in which he played straight-laced boyfriend Glen Lantz.

Set to reprise his role as Jack Sparrow in the fifth installment of the blockbuster “Pirates of the Caribbean” series, Depp, who gained fame during the late 1980s as officer Tom Hanson on 21 Jump Street, is also a guitarist, jamming with Alice Cooper and Aerosmith’s Joe Perry in their newly formed rock band, the Hollywood Vampires.

Garth Brooks (53)

Country legend Garth Brooks has come and gone on the pop culture radar through the years, and he’s definitely back now.

Brooks, whose self-titled debut record released in 1989, is one of the most popular musical acts in the history of the industry, selling more than 150 million albums. He’s a dynamic live performer as well, infusing his shows with the energy, excitement and spectacle of a top-tier rock concert (he cites Billy Joel, Journey and KISS as huge influences on his work).

Named the 1990s Artist of the Decade at the 2000 American Music Awards, Brooks spent most of the next decade in retirement. But he has come back strong this year with a string of packed-to-the-rafters shows, including seven consecutive sold-out concerts last month at the American Airlines Center in Dallas.

According to Forbes, Brooks is the top-earning country music star of 2015 and sixth overall on its annual list of highest-paid celebrities. Not bad for an “old-timer.”

LeVar Burton (58)

Actor LeVar Burton shot to fame in 1977’s iconic miniseries Roots. His career then had stops on Star Trek: The Next Generation, The Love Boat and Trapper John, M.D.

The role he’s perhaps best known for is as “literacy hero” on PBS long-running Reading Rainbow. He hosted the children’s program for 26 years and was its executive producer. He speaks often about the importance of reading in children’s lives.

In recent years, Burton was a regular guest as himself on the hit CBS comedy The Big Bang Theory. Burton launched a Kickstarter campaign and raised millions to bring back Reading Rainbow in digital format for a new generation of kids. It met its initial fundraising goal in less than 12 hours.

Reading Rainbow launched as an app in the iTunes store in 2012 and is one of the highest-ranked educational apps available.

He made headlines last month when he spoke to a sold-out symposium in Washington on the topic of talking honestly about slavery in America.

Colin Firth (55)

The hunky hero of the “Bridget Jones” movies is filming the next one, Bridget Jones’s Baby, due in 2016. It’s been 11 years since the last installment of the rom-com franchise; the series’ other male love interest, Hugh Grant, is also 55. (In case you were wondering, “Bridget” herself, Renee Zellweger, is 46; the tagline for Baby is, “The continuing adventures of British publishing executive Bridget Jones as she enters her 40s.” It also stars Patrick Dempsey, who turns 50 in January.)

Besides playing the dreamy Mr. Darcy in the “Bridget Jones” films, Firth is best known for his portraying a stuttering King George VI in the 2010 film The King’s Speech, a role that earned him the Academy Award for Best Actor. Other notable roles include an Academy Award-nominated performance in 2009’s A Single Man; a singing Harry in the 2008 big-screen version of Mamma Mia!; and the “original” Mr. Darcy in the 1995 Price and Prejudice TV miniseries.

Firth has other movie projects in the works, but for now, expect months and months of celebrity magazine photos that catch glimpses of the filming of the much-anticipated third “Bridget Jones” sequel in and around London.
