Filmation cartoon based on the live action series.

An animated series, My Favorite Martians, was made by Filmation, and ran on the primetime series' network, CBS, from September 1973 to September 1975. The series features Tim, Martin, Mrs. Brown and Detective Brennan (Brennan is considerably different). To appeal to a younger audience, Uncle Martin is joined by his Martian nephew named Andromeda, nicknamed "Andy", who only has one antenna and thus lesser powers than Uncle Martin. The pair also have a Martian pet named Okey, a sort of bouncing sheepdog with antenna. Tim also had a niece named Katy, living with them. None of the characters were voiced by the original actors; Jonathan Harris voiced Martin.
