The Days Of Wine And Roses (1962)
The Movie Drinker: Joe Clay (Jack Lemmon)
How Drunk? So drunk that even when he’s wasted, he just wants more. Hence a scene in which Joe roots around in his father-in-law’s greenhouse for more swill-worthy stuffs.
Convincing? Lemmon’s never better, subtly layering his performance with tangible spikes of tragedy. Heart-breaking.
Next Day Regrets: Loads of them, undoubtedly. It’s pretty much the reason he’s drinking to begin with.
