Samuel L. Jackson is "not ready" for a naked role.

The 62-year-old actor has a love scene in his new movie 'Mother and Child' with Australian actress Naomi Watts, but he kept his clothes on during filming.

He said: "My manager and publicist have always told me, 'You have to find a film where you get the girl. We want women that look at you and go, 'Oooh.'' I was like, 'Yeah, right, never gonna happen.'"

"There I was in bed with Naomi Watts. Maybe this will spark some whole new career arc for me. But I'm not ready for nudity. Believe me, you don't want to see all of me on a big screen. Naomi and I were going for it, but we kept most of our clothes on."

Despite not being comfortable in the nude, Sam does joke about his performance in action movie 'Snakes on a Plane' - as do other people.

He told Parade.com: "Since 'Snakes on a Plane', every time I'm in an airport, the guys scanning my bags always ask me, 'You don't have any snakes in there, do you?'

"On one flight, the pilot announced to people, 'Be aware that Sam Jackson is on board and there may be things crawling around on the floor.' I couldn't believe he actually said that over the PA. I thought, 'I hope people don't panic.' Fortunately, they laughed."
