The time-honored story line of "On The Wrong Trek" features a family vacation gone awry due to the inclusion of an overbearing mother-in-law ("Mother knows best, dear."). What sets this story apart is the sheer likability and charm of Charley Chase and Rosina Lawrence as the husband and wife on a trip that's not going to go as planned. After many misadventures (and one hilarious episode where a good samaritan's offer of gasoline ends in his car being demolished), Charley and Rosina even provide a wonderful song and dance to a group of hobos. This comedy features gentle charm and family humor that would later become a mainstay in television sitcoms (there is even a funny cameo by Laurel & Hardy, with Chase making fun of Stan). This film is a wonderful introduction to Charley Chase, one of our most overlooked and underrated comedians.
