Hollywood veteran Samuel L. Jackson hates stripping off with a leading lady onscreen as he fears she will feel insulted if she fails to arouse him.
The Pulp Fiction star has confessed he is always uncertain how to react when he has to get naked for sex scenes and bombards his co-star with a checklist of body parts he should avoid touching.
However, his biggest fear is getting too "excited" during the shoot - even though he feels he is insulting the actress by failing to respond to her passionate embrace.
Jackson tells U.K. talk show host Graham Norton, "I hate nude scenes, you have to ask where it's okay to touch and where it's not okay to touch and then you have to apologise for getting excited or for not getting excited. I'm sorry if I do and I'm sorry if I don't. It's a weird conversation to have."
The '12 Years A Slave' director will receive the accolade at the London Film Festival in October.
Critics from all over the world were asked to name the best movie of the past 16 years.
