Argo City is in inner space rather than outer space. When an eccentric man (Peter O'Toole) "borrows" a spherical object that powers the city, a young girl (Helen Slater, RUTHLESS PEOPLE) accidentally sends it soaring to the Earth's atmosphere. To save the city from doom, she goes to Earth to recover the object. In the process, she discovers (like her cousin Superman) that she is capable of super powers on Earth. One of many films often cited as one of the worst films ever made, the much maligned SUPERGIRL can't be said to be a good movie but it's much more enjoyable than its reputation would suggest. Despite its mega budget, the film has the appealing cheesiness of some of those hokey 1950s "B" sci-fi movies. I doubt it was intentional but rather "luck"! Certainly the humor is intentional and Faye Dunaway as an ambitious witch intent on world domination hits the right spots (when the doorbell rings, she snaps "It better not be those damn Jehovah's Witnesses again!"). Dunaway and Brenda Vaccaro as her apprentice provide the style and the laughs while everyone else pretty go through the motions (if they try at all). Jerry Goldsmith's thrilling score gives the film a much needed punch. Directed by Jeannot Szwarc (SOMEWHERE IN TIME). Also in the cast: Mia Farrow, Peter Cook, Simon Ward, Hart Bochner and Maureen Teefy.
