Stanley Sheff's goofy sci-fi take on Mel Brooks' The Producers is smart enough to not take itself too seriously, nor too self-consciously play up how "bad" it is. As opposed to such contrived "cult" films like the crass Sharknado series or the ineffective likes of NAKED MONSTER, GIANT PAPIER MACHE BOULDER, this one just hums along gleefully to its own beat.
The title is attributed to Orson Welles who originally was slated to play JP Sheldrake, a film mogul who buys the cheezy movie, 'Lobster Man From Mars', as a tax shelter scheme. Tony Curtis enjoyably chews the scenery as Sheldrake. Anthony Hickox and Deborah Foreman (VALLEY GIRL) play the couple who made the film within a film. Patrick Macnee and Billy Barty play actors in the crustacean epic and Bobby Pickett is the King of Mars. It's all done with tongue firmly in cheek, but, humbly and amiably so. The cast, SFX, Music, Costumes and Cinematography follow suit.
P. S. I knew a good number of people who worked on the film including lead actress Debbie Foreman and had worked with Tony Curtis. I even got to visit the set. Gives it a bit of extra nostalgia to me.
