Sean Penn does a spontaneous man kiss in "Milk"

I hope this makes the final cut.

Marc Malkin of Planet Gossip had this juicy tidbit that occured on the set of Gus Van Sant’s movie about slain gay rights activist Harvey Milk starring Sean Penn:. Performance artist Mark Martinez, who plays the late cross-dressing disco singer Sylvester in the movie, had his one-day shoot brightened considerably when he got to lock lips with Sean.

“All of a sudden, Sean’s pointing at me, and he’s talking to the assistant director,” Martinez says. “The AD comes up to me and says, ‘Just to let you know, you are now going to break up Sean and [costar] James Franco’s conversation. You’re going to grab Sean, and Sean’s going to be really excited, and he’s going to kiss you.’”

And that he did. “I’m performing, and he comes onto the dance floor,” Martinez explains. “He grabs me, and he just slaps the biggest kiss on me...It felt like the kiss was forever. I’m like, Is he going to stop? I had to close my eyes. I couldn’t believe it.”

Martinez admits to trying to convince Van Sant to do another take. “I’m thinking, We gotta do this thing again. We just didn’t get it right,” Martinez says. “But Gus was like, 'It’s perfect, perfect, perfect.' I said, 'No! It’s not perfect!' Sean was laughing at me.”

Well, who wouldn't want to get kissed by Sean Penn!
