Definitely. All the time and not just actors. I often recognize most of the other main crew people mentioned in the opening credits be it a camera man, writer, editor, production designer etc. It's just interesting to know and remember what they've done before and whether I can see their style in a movie I'm currently watching. The director is naturally the most important factor for many - and the most recognizable - but when selecting what to watch, I've made some decisions based on the writer's name as well.
