It's amazing how much of "The Kid Stays in the Picture" was done with stills, well executed, but still none the less. Actually I believe they used Robert Evan's audiobook narration and built the movie right over that. I should fact check, but I'm too tired tonight.
I found some examples of stills used in TV show openings. The really loved using it for cop and detective dramas. The music scores on these are gems as well.
