Quentin Tarantino is set to shoot his 10th film The Movie Critic this fall, and if it really is his final movie, then there are a lot of unproduced Tarantino projects that will never see the light of day. Set in Los Angeles in the 1970s, The Movie Critic will revolve around an eccentric film reviewer making the rounds in the New Hollywood era. For a while now, Tarantino has asserted that he’ll retire from filmmaking after his 10th movie, because he believes that directors get worse with age and he wants to avoid the same fate.
