Steve Gordon’s 1981 comedy seems to have been inspired by a screening of Holiday, after which someone asked, “Why couldn’t Cary Grant have Katharine Hepburn and the money?” The answer, of course, is that the need for choice gives the film a much finer moral and emotional point; without it, it would just be a grubby fantasy. But Arthur, alas, never rises to even that level: so little care has gone into the characterizations, the structure, and the situations that the film merely feints at significant comedy. Dudley Moore is the rich boy in love with poor girl Liza Minnelli, though all of the film’s feeling is in his relationship with his flinty butler, John Gielgud. With Geraldine Fitzgerald, Jill Eikenberry, and Anne De Salvo.
