Since a male full-frontal nude scene happens, oh, every five years or so, it’s a little difficult to determine how male celebrities “measure up” against each other. Luckily, the randy reputations of the superstars below precede them. From Old Hollywood icons to today’s hottest actors, we’ve got the dirt on the 15 fellas who are famed for “going the distance.”

The Largest Penises in Hollywood #1: Daniel Craig

This just in: Daniel Craig has a large penis. Just ask Judi Dench.

The distinguished Dame Dench offered this not-so-distinguished quote after catching an eyeful of her Casino Royale co-star’s, er, “License to Kill” thanks to a conveniently placed trailer opposite his: "It’s an absolute monster! Maybe I shouldn’t have said that. How uncouth of me!"

Craig’s snug bathing suit scene should also eliminate any doubt that he’s more of a 009 (at least) than a 007, don’t you think?

The Largest Penises in Hollywood #2: Liam Neeson

Indeed, Dickinson has claimed that the 6’4” Neeson has “the biggest penis of any man alive,” which should make you feel slightly dirty next time you watch Schindler’s List.

The Largest Penises in Hollywood #3: Mark Wahlberg

For the record, Wahlberg says he’s a “decent size,” something to which those who remember his 1990s Calvin Klein underwear ads can attest. Still, once you’ve appeared on film with a super-sized prosthetic penis, it’s hard to go back to normal life. Says Wahlberg, “It's a bit embarrassing when I go into a locker room or take a pee in a bar because guys try to check me out. That's always weird."

Victoria Beckham has long bragged about hubby David Beckham’s giant “goalkeeper,” but we civilians had to see it to believe it. And see it—and believe it—we did when Beckham appeared in Giorgio Armani’s recent ad campaign, clad in nothing but a teeny pair of whitey tighties threatening to burst open at the seams. That thing is larger than his wife!

The Largest Penises in Hollywood #5: Milton Berle

Turns out the most famously endowed male celebrity in Hollywood history is someone best remembered (by our generation) as that Alzheimer’s patient befriended by Steve Sanders on “90210.” Yep—we’re talking about Milton Berle. The late comedian was apparently the Dirk Diggler of his day, boasting a penis that is rumored to have been—gulp—14 inches long.

Many might agree that actor/musician Jared Leto is a big dick. Apparently, however, he also has one. At least that’s what adult film star Corina Taylor claims, saying that Leto, who had “the most [she] ever had to work with,” could have a “second career available for him if he ever runs out of mainstream work."

They don’t call Owen Wilson the Butterscotch Stallion for nothing. And unless he’s smuggling a mango in his boxers in an effort to amuse pal Woody Harrelson, Owen’s got some serious man fruit. (Between that and his massive nose, it’s a wonder the poor guy doesn’t tip over.)

The Largest Penises in Hollywood #8: Brandon Routh

According to EntertainmentWise.com, film execs had to use digital technology to downplay Routh’s superhero-sized package so as not to frighten little kids in the audience. Says a source, “It's a major issue for the studio. Brandon is extremely well-endowed and they don't want it up on the big screen. We may be forced to erase his package with digital effects."

Perhaps Routh should have been cast as Batman instead. Think of the money they’d save on codpieces!

If you’re going to be named “Roddy,” it helps to have a big penis—and reportedly this Planet of the Apes star did. According to Greta Garbage’s Outrageous Bathroom Book, McDowell wasn’t just long—he was practically a contortionist! The late actor was known for “entertaining” friends by performing auto-fellatio. Who knew he had so much in common with Ron Jeremy?

Ol’ Blue Eyes didn’t disappoint in the girth department either. Former wife Ava Gardner is reported to have quipped, “He only weighs 120, but 100 pounds is cock.”

And according to ContactMusic.com, Frank Sinatra’s valet claims that the crooner had to have his underwear custom-made to accommodate his Sinatra Jr.

“Miami Vice” star Don Johnson didn’t just have sexy stubble, a scorching-hot music career (cough), and a chic pastel wardrobe going for him. Greta Garbage’s Outrageous Bathroom Book asserts that Johnson’s, ahem, johnson is as big around as a beer can. Is this why two-time ex-wife Melanie Griffith went to rehab?

The Largest Penises in Hollywood #13: Steve McQueen

Charlie Chaplin may have not needed that cane after all. Chaplin’s large penis—once dubbed the “Eighth Wonder of the World”—is still revered decades after his death.

The Largest Penises in Hollywood #15: Errol Flynn
