Improvised around standing sets at the Texas State Fairground, Edgar G. Ulmer’s deep-discount science fiction film (1960) projects his themes to a barren, blasted future, where a visitor from the 20th century (Robert Clarke) is trapped in an underground city of sterile postnuclear mutants (some from stock footage lifted out of Island of Lost Souls). Even on this despairing level of fly-by-night filmmaking, Ulmer’s treatment remains resolutely personal, and the film, though visually slack, emerges as something terse, resourceful, and expresively icy. With Darlene Tompkins, Arianne Arden (Ulmer’s daughter), and Vladimir Sokoloff.
