(written from a Production point of view)
During his forty years career in acting, Frankham mostly worked on television. He guest starred in series such as Alfred Hitchcock Presents and The Outer Limits - including "Nightmare" (with Willard Sage, Bernard Kates, John Anderson, Whit Bissell and Vic Perrin, written by Joseph Stefano, and directed by John Erman) and "Don't Open Till Doomsday" (with John Hoyt and voice work by Bob Johnson and the host Perrin, written by Stefano and directed by Gerd Oswald). In the latter episode, Frankham's character was menaced by an alien in a box a la his Trek appearance.
He also appeared in Thriller, Medical Center, 12 O'Clock High (starring Robert Lansing and Frank Overton, including "The Trap" directed by "Is There in Truth No Beauty?" director Ralph Senensky), McCloud, The Six-Million Dollar Man, and The Waltons.
