The main characters in 'First Man On Mars' first appeared in Mike Lyddon's (with John R. Woods) 1980 super-8 horror-comedy 'Mutilation Maniacs'. In that film, 'Dick Ruffman' was the Chief of Police, rather than the Sheriff. The coroner in 'First Man On Mars' is named Fritz Leiber. In 'Mutilation Maniacs', the virtually identical character is named Fred Sadizmo. FMOM's deputy 'Jordy Sample' was a character developed (with that name) for an unmade sequel to 'Mutilation Maniacs' called 'Invasion Of The Water Devils'. 'Mutilation Maniacs' was released as an 'extra' on Lyddon's 'Night For Nixie' DVD.
