The fine presence of the marvelous Helen Slater redeems this last film in the Salkind Superman franchise, which we’re told features the first live- action theatrical film super-heroine was. CineSavant likes the show for the right reasons — his very young kids adored it — and can see its turnip screenwriting and frayed corners showing through. The release combines a 125-minute Blu-ray with an overstuffed 139-minute DVD. Also starring Faye Dunaway, Brenda Vaccaro, Peter Cook Marc McClure, Hart Bochner, Maureen Teefy, Peter O’Toole, Mia Farrow and Simon Ward. On Blu-ray from The Warner Archive Collection.
