At any level would you say that with no prior knowledge of the quality of something, you can say that a certain person being in it will make you want to watch it? I try to think of myself as being above this sort of thing, as I typically can't think of 5+ films that most of the biggest actors around have been in, but right now I'm so enamored with Dr. Who that I think I'd watch anything with David Tennant or Matt Smith in it.
