San Quentin (1937)

Good guy Pat O'Brien is as the reform minded prison guard trying to help Bogart - a con who wants to go straight but can't. Ann Sheridan (11 years his junior) plays Bogie's older sister (!). The film zips along and at 70 minutes doesn't outstay its welcome. Summary: A good little WB prison drama, nothing special except for the strong cast. Enjoyable. Rating **1/2
