Quentin Tarantino is adamant that The Movie Critic will be the last movie he ever directs, so that means there's just one last chance for him to collaborate with any new actors. Throughout his career, Tarantino has worked with a few actors multiple times. Christoph Waltz, Samuel L. Jackson, Tim Roth and Brad Pitt are just a few of Tarantino's regulars, and it's likely that some of these familiar faces will also make an appearance in The Movie Critic. However, Tarantino's movies often feature large casts, so there is always room for new actors to enter into the mix.
