Cast as Doctor Fendleman in Doctor Who:Image of The Fendahl but dropped out. Dennis Lill took the role.
He portrayed "Harry Kane" in "The Avengers" (1961) episode "The Avengers: Tunnel of Fear (#1.20)" (1961) after Murray Hayne dropped out at the last minute. Because the article in the TV Times listed Hayne as the actor who had played Kane - by the time Bate was brought in, it was too late to change the listing - Hayne was thought to have portrayed Kane for over fifty years.
