If sincerity counts, this 1976 feature is Peter Bogdanovich's finest film—it's about loving movies, an emotion Bogdanovich knows better than most. But his story of Hollywood's dawning days—with the details drawn mainly from Bogdanovich's excellent interviews with pioneer directors—is cursed with a clumsy narrative, awkward dialog, and a cast that literally falls down a lot. Bogdanovich is trying to do an interesting and commendable thing in dramatizing aesthetic passion; his failure is as noble as it is conspicuous. With Ryan O'Neal and Burt Reynolds. PG, 121 min.
