Did You Know?


This is one of 54 Hopalong Cassidy features produced by Harry Sherman, initially distributed by Paramount Pictures from 1935-1941, and then by United Artists 1942-1944, which were purchased by their star William Boyd for nationally syndicated television presentation beginning in 1948 and continuing thereafter for many years, as a result of their phenomenal success. Each feature was re-edited to 54 minutes so as to comfortably fit into a 60 minute time slot, with six minutes for commercials. It was not until 50 years later that, with the cooperation of Mrs. Boyd. i.e. Grace Bradley, that they were finally restored to their original length with their original opening and closing credits intact.

This Hopalong Cassidy film Mystery Man has Hoppy dealing with the Bud Trilling gang. The title of the film comes from the fact that while we know that Trilling is actor Don Costello he's not known to anyone other than his gang. No wanted posters with likeness are circulated so consequently he can move around pretty freely.

Bill Boyd, Jimmy Rogers, and Andy Clyde at the beginning of the film happen to be in town when the gang pulls a holdup at the bank and in a very thrilling gun battle they're captured and hauled away to jail. Costello frees them however and the rest of the movie is a running battle between the Bar 20 crew and the Trilling gang. Costello is a resourceful foe, but you know comes out on top.

Costello certainly regretted he and the gang decided to diversify from holdups to cattle rustling.
