A Gentleman at Heart is a 1942 romantic comedy film starring Cesar Romero, Carole Landis, and Milton Berle. A bookie acquires an interest in an art gallery. Plot Lucky Cullen (Milton Berle) gets into trouble when his boss, bookie Tony Miller (Cesar Romero), finds out that Lucky has bet (and lost) $5000 under a false identity. Tony gives Lucky 24 hours to settle the debt. Lucky learns that he has inherited a Fifth Avenue art gallery from his uncle. When he and Tony check it out, however, Helen Mason (Carole Landis) informs them that the business is so far in debt it is worthless. Attracted to Helen, Tony cancels Lucky's debt in exchange for the gallery. He takes Helen out to dinner and gets her to start teaching him about art. When Tony finds gallery employee Stewart Haines (Richard Derr) kissing Helen, he sends Stewart on a buying trip to Europe.

Further complications arise when Stewart returns from his trip with Don Fernando (Steven Geray) and the genuine painting. After Lucky kidnaps Don Fernando, a worried Tony buys the work for $100,000, then switches it with Gigi's forgery, only to have the government expert dismiss it as a bad copy. Helen insists that other experts be brought in. While they wait, Tony confesses the truth to her. Meanwhile, Gigi substitutes his (much better) forgery, and the new experts are satisfied it is genuine. To show Helen that he
