Allen also produced several TV movies, such as City Beneath the Sea, which recycled many props and Models from Voyage, Lost in Space, and Man From The 25th Century. Both were intended as pilots for new TV series projects, but his small-screen success from the 1960s largely eluded him in the 1970s. Lost in Space's Bill Mumy said of Allen that, while he was very good at writing television pilots that sold, his unwillingness to spend money hurt his shows' quality once on the air. A Monster costume that appeared on one of his shows, for Example, would appear on another a few weeks later with new paint. Writer Jon Abbott described Allen as paradoxical. "Here was a man who, when told the cost of a spaceship for a Lost in Space alien, snapped, 'Let him walk!' ... and then let the show be canceled rather than take a cut in the budget".
