For those that don't know, M:I was the sister production of TOS, produced side by side after both were given the green light by studio boss Herb Solow at Desilu in the mid 60's. I found Season 4 of M:I in a bargain bin and thought I'd give it a go, mainly out of curiosity about Leonard Nimoy's acting in some rare non-Trek work. I have to say this show is actually quite clever, if a bit repetitive. Some episodes are actually quite suspenseful, others had me reaching for the remote out of boredom. Nimoy's character is a magician named Paris who is skilled in the art of vocal impersonations and disguise - in some episodes the villain he impersonates is played by Nimoy under clever (and sometimes not-so-clever) makeup. Some of his work is hilarious - particularly his attempted accents (still not sure if he was supposed to be a British or Australian sailor in one episode, but god it was funny). In one episode he sports a giant wig while off duty, sitting around at IMF headquarters for some unknown reason. The TOS connections are everywhere in casting and locations. Vasquez Rocks and the Paramount backlot appear regularly. In just the dozen episodes I've seen, I've noticed the actors who played Commodores Mendez and Stone, The Proconsul, Salish, The male Scalosian, Anan 7, Losira, Sylvia, and others. In one episode Paris is given an agent of similar appearance to help him out on a mission, and it is none other than his stand-in from TOS (Frank Da Vinci, aka Lt. Brent)! "Ah...excellent..a similar bone structure", Paris notes. M:I Season 4 was made in '69/'70, and gives a glimpse of how TOS may have looked in the early 70's had it gone on for a fourth season, and is worth a look for playing spot-the-ex-TOS-actor if you can pick it up on the cheap.
