My Favorite Martian launches its third and final season with its first color episode, and its first (and only) two-part story. In his efforts to return to the moment just before he crash-landed on earth in 1963, Uncle Martin (Ray Walston) deploys his Cathode-Ray Centrifugal Time Breakascope--which hurls himself and Tim (Bill Bixby) way, WAY back to the St. Louis of the year 1849. Here the two time-travellers meet Marshal Brennan (Alan Hewitt), great-grandfather of Martin's perennial nemesis Detective Brennan (also Alan Hewitt), who upholds family tradition by arresting the duo as counterfeiters when they try to pass 20th Century currency. Later on, Tim and Martin confront the great-grandmother of their landlady Lorelei Brown (both roles played by Pamela Britton)--and promptly make a mistake that could grievously alter the course of the future!
