Cast as Sheriff Justice in the film, Gleason proved why he was one of the greatest actors of his era. Believe it or not, most of the lines Gleason recites in the movie were entirely improvised!
It takes a great deal of talent to be able to make material up on the spot like that. But Gleason was a pro at it, and his performance benefited as a result.
