Signed up by MGM's dramatic school directly after graduating from the University of Southern California.
Possessed one of the most distinctive voices in the industry. However, unlike other actors with distinctive voices--i.e., William Woodson, Art Gilmore, Reed Hadley--Millican never used his for voice-overs, narrating documentaries and/or trailers.
Appeared in hundreds of westerns and was a close associate of cowboy
star "Wild" Bill Elliott, staging a number of personal-appearance rodeos on Elliott's behalf.
