Actor Armie Hammer has a man-crush on his J. Edgar co-star Leonardo DiCaprio.

Hammer and DiCaprio star in the upcoming Clint Eastwood-directed film of the life of FBI director J. Edgar Hoover. Filming for J. Edgar began last month in Los Angeles.

DiCaprio is playing the lead role in the movie, while Hammer, the 24-year-old co-star of The Social Network, plays Clyde Tolson, Hoover's co-worker and alleged lover.

J. Edgar screenwriter Dustin Lance Black has promised a “tender” kiss for the men.

In a brief videotaped interview on the Oscar's red carpet with's Jon Chattman, Hammer was asked if he had a man-crush on DiCaprio.

“I got to say, it's hard to spend as much time as I do with that guy and not develop a man-crush. He's an incredible dude,” he said. (The video is embedded in the right panel of this page.)

Hammer agreed that Pauly Shore and Andy Gibb would be worse options than DiCaprio.

Earlier, Hammer told reporters that he's ready for a “ton of kissing scenes” with DiCaprio.

The film also stars Denis O'Hare (True Blood), Josh Lucas (Glory Road), Ed Westwick (Gossip Girl), Naomi Watts (King Kong) and Judi Dench (Casino Royale).
