Caligula is also a career curiosity for author Gore Vidal, who wrote the original screenplay, but later demanded his name be removed from the credits, and venerable actors Peter O'Toole, appearing briefly as the syphilitic Emperor Tiberius Caesar, and John Gielgud as Nerva, a Senator who'd rather take his own life than "live with this reptile." This controversial film's tortured history is untangled in a very helpful booklet that is packaged along with this set's three discs. One is hard-pressed to think of a more reviled film graced with such a gala presentation, but Caligula's defenders and the curious will be amply rewarded with both the original uncut theatrical version of the film and a re-edited alternate version. Supplementary material includes an hour of deleted footage, a pretentious "making of" documentary made during the film's production and a new interview with director Tinto Brass, whose softcore tendencies clashed with Guccioni's more extreme vision (Brass did not have final cut, allowing Guccione to insert more explicit footage into the film). McDowell contributes his own lively audio commentary. "God help us," he groans as the film begins, but by its bloody conclusion, he proclaims he has "no regrets at all" about making the film. Caligula, Mirren maintains, is "an irresistible mix of art and genitals." And you've got to hand it to Guccione. Especially in these politically correct times, it is still strong and scandalous stuff. --Donald Liebenson
