Johnny Depp was worried that his manhood wasn't big enough for his new role.

Oh dear.............

Johnny Depp feared he’d be left lacking when he took on the role of the reportedly very well-hung John Dillinger in new movie Public Enemies.
But after extensive research the Sweeney Todd star was relieved to learn that the U.S. Depression-era hood’s impressive manhood is probably a myth.
He tells the new issue of Rolling Stone magazine: "There's some very famous photographs of Dillinger on the morgue slab, and there's one particular angle, with the sheet over him, and it's (his penis), like, 25 inches, man.
"The speculation was that he was in the wrong racket. But you read further, and it was a crank on the other side that the sheet had been draped over, making it look like he was packing, you know, Mr. Ed's (U.S. TV talkinghorse) shotgun (penis)."
