One of the Best Episodes- Cliff Robertson
Cliff Robertson was the special guest star in one of the best episodes of the series. It was called "The Underground Railway," and Robertson played a hood who had plastic surgery to fix his ugly face and disguise himself. It was a great episode and aired originally in the first season.
Robertson was a fine actor. I liked him in "Charly," (where he won the Academy Award for Best Actor)and in the film he did with Genevieve Bujold- "Obsession".
Not only did "The Untouchables" have a fine cast in Robert Stack as Ness and the other good guys, but the guest stars each week really made the series outstanding.
