In the days before I was exiled by the HTP (Hollywood Thought Police), I wrote screenplays for several comedy stars. The greatest of those, without doubt, was the late Richard Pryor, thought by many (including me) to have been the greatest stand-up comic of all time.I wrote the script for the film Bustin' Loose for Richard and, while working on the revisions, traveled with him across country while he was on tour.
