In 1960, Bissell had appeared in George Pal's production of The Time Machine, as Walter Kemp, one of the Time Traveller's dining friends. He also appeared in a 1978 TV movie adapting the H. G. Wells novel for a more modern setting. Bissell's Time Tunnel co-star, John Zaremba, also appeared in the telemovie. Thirty-three years later, in 1993 the documentary film Time Machine: The Journey Back (which featured Bissell, Rod Taylor and Alan Young), Bissell recreated his 1960 role as Walter in the opening sequence. It was Bissell's last acting performance.
