It Happened Tomorrow is a 1944 American fantasy film directed by René Clair, starring Dick Powell, Linda Darnell and Jack Oakie, and featuring Edgar Kennedy and John Philliber.

After work, he and his co-workers go to see a mind-reading act starring the "Great Sigolini" (Oscar Smith) and his beautiful assistant Sylvia.

He spots the man who stole his money and chases him on foot through the streets and over the rooftops, until they both fall through the chimney that leads to the very hotel lobby he's been trying to avoid.

Director and producer Frank Capra originally purchased the rights to Hugh Wedlock and Howard Snyder's story, but when he discovered the concept was similar to that in Lord Dunsany's 20-year-old one act play, he bought it as well; later, when he was going into the Army to serve in World War II, he sold both to Arnold Pressburger.

[2][3] Clair initially wanted Cary Grant for the lead role, but wound up with Dick Powell, who was on the verge of altering his screen persona from a lightweight musical-comedy "juvenile" to a harder one, playing tough guy private detective Philip Marlowe in Murder My Sweet later that year, followed by a series of film noirs.

The ending, especially, which hinges on a mistake in the newspaper from the future, had a personal connection for Clair, since he was fired from his first job as a reporter when he made up a story which was the opposite of what actually happened; Nichols was a former newsman as well.

[3] Robert Stolz was nominated for the Academy Award for Best Music, Scoring of a Dramatic or Comedy Picture, while Jack Whitney was nominated for Best Sound, Recording[5] It Happened Tomorrow was adapted as a radio play for the July 3, 1944 episode of Lux Radio Theater with Don Ameche and Anne Baxter,[2] the September 25, 1944 episode of The Screen Guild Theater with Dick Powell and Linda Darnell reprising their original roles and on the October 9, 1946 episode of Academy Award Theater, starring Eddie Bracken and Ann Blyth.
