Night Life in Reno (1931)

'Night Life in Reno' is a low budget 'pre-code' film from something called 'Art Class Picture Corp'. The most notable actor in it is probably Dixie Lee, the first wife of Bing Crosby and at the time this picture came out the bigger star. Even so Dixie's is basically a bit part, the lose woman a Los Angeles husband (Jameson Thomas) strays with, prompting his wife (Virginia Valli) to flee to Reno for a six week divorce. Thomas goes after her in an attempt to stop the divorce, he says he is regretful but Valli needs him to prove it, which he does in the final reel. 

This starts as a melodrama, has a protected comic drunk/ awkward double date scene (the other parties have no idea the two are married). and ends after Thomas falsely confesses to a murder that Valli has been framed for. Of course the real killer is apprehended very shortly thereafter and the central couple reunited. Not great, but not as bad as it might have been given the poverty row production. Gambling was legalized in Nevada earlier the same year as this picture was released, so it's the only movie I've seen set there during that 2 or 3 year period were open gambling was legal in Nevada, but liqueur was not because of probation. **
