This is just a good, clean, fun movie with an excellent cast. It was shot back in the 1970's. It is amazing that the movie did not do better at the box office, because of all the stars that were cast in it. It is interesting to note that this movie was shot mostly in Mansfield, Ohio at the Mansfield Reformatory. Since then, Shawshank Redemption and Con Air were filmed there as well. The prison used for the movie has since been replaced by a new one and is now an historical site, open to the public. I think you will find some good laughs here. It is not brain surgery and a great way to experience some top stars in one package. I was an extra in this movie, playing both a prison guard and a prisoner. Chasing James Caan and Elliot Gould was a hoot. The cast and crew of this movie had a great time filming it. I might add that the director, Mark Rydell, went on to direct the movie,On Golden Pond.
