Quentin Tarantino’s short film Reservoir Dogs, that would latter be expanded into feature film of the same name in 1991

This is from the Sundance Director’s lab, and according to a Redditor, they have volunteers work as the film crew and let screenwriters workshop scenes from their script and have advisors come in and give them advice on how they are shooting things, directing actors, blocking action.

This can now be found on the Reservoir Dogs’ 10th anniversary special edition DVD.
