'Oh my God! There she is' screams Ignatius Reilly, the film buff who loves to fan his pet hates in John Kennedy Toole's A Confederacy of Dunces. She, of course, is Doris Day, here involved in the direst of circus plots ('What degenerate produced this abortion?' asks the indignant Reilly; answer, Hecht and McArthur). A former choreographer and a fine hand at musicals (Good News, Easter Parade, Summer Stock), Walters almost makes up for the three-ring vulgarities with some beautifully staged Rodgers and Hart numbers, although the best of them (the opening sequence) clearly reveals the hand of Busby Berkeley, credited as second unit director.
