Two movies I know of are titled The Rounders:" one is a 1914 Charlie Chaplin silent;
the other is a 1965 comedy/western with Glen Ford and Henry Fonda.
In both films the title characters are sympathetically displayed as lovable drunks.

The Fonda/Ford film is (inexplicably) one of my all-time favorites, unrelievedly corny as it is.
The VHS tape is hard to find and fetches a high price on eBay, but a DVD is available here for $14.99

The Chaplin film can be viewed for free here.
