George Vincent "Skip" Homeier (5 October 1930 – 25 June 2017; age 86) was 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, and his scenes for "The Way to Eden" between Friday 22 November 1968 and Friday 29 November 1968 at Stage 9 and Stage 10. He was also called in for a makeup and costume test on Thursday 21 November 1968 at Stage 9.
Outside of Star Trek, Homeier 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 were 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 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).
