Several characters in this film make it difficult to like. The worst of these is the leading man (Pat O'Brien). He is very abrasive, rather mean-spirited, fast-talking and an alcoholic! In fact, there's really little to recommend this guy. Additionally, Leo Carillo plays a guy who is a cheat and a thief. With characters like these, it's hard to understand what was going through the writer's mind when they created this bizarro film.
"In Caliente" begins in New York. Larry McArthur (O'Brien) is awakening from a bender and this friend and business partner Harold (Edward Everett Horton) marvels that the drunk writes his theater reviews without even going to see the performances! You assume it's because he's an alcoholic jerk and soon he's drunk again--dead to the world after drinking a bottle of whiskey. Harold is concerned about Larry's self-destructive life as well as his upcoming wedding to a gold-digger (Glenda Farrell) he barely knows, so he whisks the unconscious Larry to a resort town in Mexico, Caliente, to dry him out and get him away from this girl. Unfortunately, Rita Gomez (Delores Del Rio) is there performing--and Larry savaged her some time ago in one of his reviews. Naturally, he also never saw her in person and he truly deserves her to destroy him--which she plans on doing. However, over time they start to fall in love with each other--though I have no idea why. Why would he love her--she's not a whiskey bottle! And, he is just nasty and a drunk--and what sane woman would want that?! For comic relief, we have Horton, though he isn't really used well here. His role is more serious than usual. Also, Leo Carillo plays Rita's uncle. As I mentioned above, he's pretty much a thief and this alone is supposed to make him funny--it didn't.
In addition to the romance and comedy, there is a lot of music and dancing--particularly later in the film. These production numbers are the typical Busby Berkeley sort of thing--where the dance numbers are too large for a stadium, let alone a nightclub! One number in particular is notable. "The Lady in Red" is a shockingly risqué number--with very sexily clad ladies who look much more Pre-Code than what you'd expect in 1935 when things were SUPPOSED to be much more sanitized. Oddly, however, the sexiness and beauty of this routine is pretty much ruined when Judy Canova inexplicably enters and begins singing like a slow-witted hillbilly....in Mexico! Huh?! Interestingly, the song morphed into a HUGE and very long production number that lasted a whopping 20 minutes--too long, much too long for my taste.
So, we have unlikable characters, alcoholism, musical numbers that are too long and comedy that isn't very funny. Overall, a complete misfire and waste of talent. See it if you must, I think pretty much everyone in the film did better films than this.
