Arthur (1981): Arthur Bach is one of the last functioning "funny drunk" examples of this trope before changing attitudes towards alcohol use in The '80s made such portrayals come off as in bad taste. His near-constant drinking is a symptom of his Lonely Rich Kid / Manchild nature; while it is mostly for pleasure (he's Fun Personified), some of it does have more serious motivations — he tells his valet that he's not going to go to a meeting with his humorless father sober. He is capable of completely abstaining from alcohol while he tends to said valet, who is dying, but he does sink into a bout of Drowning My Sorrows afterward. At one point, his valet points out that he can afford to be an eccentric drunk because he's so wealthy; otherwise he'd be a typical gutter drunk. With that in mind, in the sequel Arthur 2: On the Rocks as he goes from Riches to Rags his alcoholism becomes much more of a problem, and part of earning his happy ending is finally getting on the wagon on a long-term basis. The 2011 remake of the original film also treats his situation more seriously, with Arthur being pushed to attend Alcoholics Anonymous meetings.
