Keep the Change (2017) was written and directed by Rachel Israel.
It stars Samantha Elisofon as Sarah and Brandon Polansky as David. This film could be called "Romeo and Juliet," because Sarah and David are star-crossed lovers. Sarah loves David in her way, and David loves Sarah, in his way. The problem is that their ways don't always match.
I was really moved by this movie, because both leads are, indeed, on the autism spectrum. Director Israel took a leap of faith that her actors would come through, and they did. It was wonderful to realize that Elisofon and Polansky didn't just watch people on the spectrum, and then try to act like them. They themselves don't have to fake it, but being on the spectrum doesn't always allow people to demonstrate their skills. Both of them are wonderful actors, and director Israel had the talent to make us appreciate their acting.
We saw this movie at the excellent Dryden Theatre in the George Eastman Museum. It was part of the wonderful Rochester Jewish Film Festive. It will work well on the small screen. Keep the Change has a terrible IMDb rating of 6.3. Did the people who rated the film see the same movie that I saw? Find this movie and watch it. You won't be disappointed.
