Actor Samuel L. Jackson enjoys watching his films in public movie theatres so he can gauge fans' reactions to his work.

The Pulp Fiction star admits his impromptu appearances often cause a stir.

He tells the London Evening Standard's ES Magazine, "I grab my popcorn and my big slushie and I sit on the end of a row, up high so I can see people’s reactions. They normally spend the first half hour tweeting, and then they calm down."
