Co-star: 'Penn kiss lasted forever'

Mark Martinez has claimed that his screen kiss with Sean Penn felt like it lasted "forever".

Martinez filmed scenes as a cross-dressing disco star called Sylvester in Penn's new film Milk.

Speaking about the kiss, he told E!: "I'm performing, and Sean comes onto the dance floor. 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 just couldn't believe it!"

He added: "I wanted to do another take, I'm thinking, we gotta do this thing again. We just didn't get it right.

"But Gus [Van Sant, the director] was like, 'It's perfect, perfect, perfect.' I said, 'No! It's not perfect!' Sean was laughing at me during the scene!"

Milk tells the story of Harvey Milk, California's first openly gay official.
