(written from a Production point of view)
George Vincent "Skip" Homeier (born 5 October 1930; age 86) is an actor who played two different characters in two episodes of Star Trek: The Original Series: Deputy Führer Melakon in "Patterns of Force" and Dr. Sevrin in "The Way to Eden". He filmed his scenes for "Patterns of Force" on Monday 4 December 1967 and Tuesday 5 December 1967 at Desilu Stage 10.
Outside of Star Trek, Homeier has co-starred in such films as The Gunfighter (one of his many Westerns) starring Gregory Peck, The Ghost and Mr. Chicken starring Don Knotts, and the original acclaimed made-for-TV movie Helter Skelter, in which he portrayed Judge Charles H. Older, before whom Charles Manson and others were tried. Most of his credits are made up of Westerns and war films.
Playing Doctor Sevrin was not Homeier's first experience with facial prosthetics in a genre show: he wore them in a 1964 episode of The Outer Limits directed by Gerd Oswald called "Expanding Human" (which featured James Doohan, Keith Andes, Jason Wingreen and Peter Duryea).
He has also appeared in numerous other television series, including Voyage To The Bottom of The Sea, Lost In Space, Rawhide, Perry Mason, Bonanza, Mission: Impossible, Fantasy Island (which starred Ricardo Montalban), and Quincy, M. E. (which starred Garry Walberg and Robert Ito).
