Mr. Lucky is a 1943 romance film directed by H.C. Potter, starring Cary Grant and Laraine Day.

It recounts the tale of an attraction between a shady gambler and a wealthy socialite in the days prior to the United States entering World War II.

When a new night watchman (an uncredited Emory Parnell) notices her and fears she is about to jump, Swede stops him from bothering her.

First, he and his treacherous partner Zepp have received draft notices to join the army in preparation for World War II.

He talks the head of the local War Relief organization, Captain Veronica Steadman, into authorizing him to run a "charity" casino, promising to raise enough money to outfit a relief ship, despite the suspicions of her lieutenant, wealthy socialite Dorothy Bryant.

At one point, Joe teaches Dorothy Australian rhyming slang, for example, "tit for tat" (hat), "twist and twirl" (girl), "storm and strife" (wife).

She wrote to tell her son that when German paratroopers landed nearby, under his brothers' leadership every man in their village fought to the death.

When Joe shows up at the other end of the pier, he wants to go out on the town to celebrate their last night in port rather than going back to their ship.

A 1959 TV series, Mr. Lucky, was supposedly based on this film, but they have virtually nothing in common apart from the fact that the lead character is a gambler and owns a boat.

Creator Blake Edwards confirmed that it was reworked from "Dante's Inferno," a recurring element of Four Star Playhouse that he had originated.
