In The Amazing Colossal Man, Manning is portrayed by Glenn Langan (credited as Glen Langan), who appeared as Captain Ross in Women of the Prehistoric Planet, and also had a recurring role as Victor Tribolet in the TV series Hondo. In War of the Colossal Beast, Manning (who is disfigured and unable to speak) is portrayed by Duncan "Dean" Parkin. In both MST3K episode segments, Michael J. Nelson cameos as Glenn, ostensibly taller than 60 feet as he's able to reach the Satellite of Love.
