Before "Hogan's Heroes", the future Col. Wilhelm Klink (Werner Klemperer, son of famed conductor Otto Klemperer) guest stars as an apparent crackpot mining/railroad engineer.
This episode is one of a handful in the "Maverick" series that uses actual names of real locations. This action in this first-year episode occurs in Virginia City and Carson City, Nevada and aired at least two years before the premier of the "Bonanza" series. As such, it lacks the consistent tongue-in-cheek humor of a few of the earlier and most later episodes (with one exception, beware a woman who has a gun and knows how to use it). But seeing Col. Klink without accent and monocle is worth the 50 minute time investment.
