In ‘See You Yesterday,’ time-traveling science nerds try to prevent a police shooting

Imagine a movie that’s a mash-up of “Back to the Future” and Spike Lee’s “Do the Right Thing.” That’s the elevator pitch for the new film “See You Yesterday.” In fact, Spike Lee produced it. The film is about two high school science nerds who invent time-travel, and try to go back in time to prevent a police shooting.
