For Star Trek: The Original Series, matte paintings were usually on glass and were backlit. (Trek: The Unauthorized Story of the Movies, p. 42) Even they were too costly for frequent use in the series, though they always increased visual scope to an episode. ("The Menagerie, Part I" text commentary, TOS Season 1 DVD) All the matte paintings for TOS were done by Albert Whitlock. [1] He noted, "I only had about a week to do each one, mostly futuristic architecture." (Cinefantastique, Vol. 27, No. 11/12, p. 72) The scenes that the paintings represented include: * Rigel VII ("The Cage" ) ) )
