Chalk is a 2006 comedy mockumentary about teaching focusing on the lives of three teachers and one assistant principal. It stars Chris Mass as Mr. Stroope and Troy Schremmer as Mr. Lowrey. It is directed by Mike Akel. The movie is based on both Akel's and Mass' real life experiences in the teaching profession. Co-written by Mass and Akel, the film was developed through improvisation all the way through the process, from writing through production and post-production. The final film was edited together from more than 60 hours of footage.
