Invisible Creature was broadcast, for example, in the 1960s on WIIC-TV in Pittsburgh on the 'monster movie' programme Chiller Theater on 23 July 1966 and 2 August 1969. It was also shown on WFLD-TV in Chicago numerous times during the 1970s: on Screaming Yellow Theater on 27 October 1972 and 2 March 1973; on WFLD Chiller Theater on 29 June 1975, 4 April 1976 and 15 August 1976; and on Monstrous Movie on 16 April 1977. More recently, the film was shown as The House in Marsh Road, its British title, on Talking Pictures TV in the UK on 11 October 2019.
