Arthur
Another of those Neil Simon/Samuel Goldwyn-type comedies that has much more acclaim than it deserves. A rich and shallow nitwit, Arthur (Moore, playing so many scenes of Arthur drunk it became his trademark shtick), falls in love with a commoner (Minnelli), and for some reason I can't even remember, has to choose between the two. John Gielgud is a sarcastic butler who takes care of him.
There were probably a few laughs I could remember if I really tried, but nothing makes me want to remember much about the whole film.
