For years the "Hot Choc'late Soldiers" animated sequence, created by Walt Disney Studios, could not be shown as part of this movie, because in 1934 Disney had licensed only movie-theatre rights and had reserved the sequence's TV rights for his own company. Finally, in 1992, Ted Turner's company, which then owned the rights to the MGM archive, settled with the Disney company and released a video version of the film containing "Hot Choc'late Soldiers". [Unfortunately, the transition scene, with Mickey Mouse at the piano in B&W and the "Hot Choc-late Soldiers" sheet music in Technicolor, was not properly reconstructed, so only the Technicolor portion of the scene is visible. NOTE: while the previous sentence may have been true in 1992, the movie now contains the B&W transition scene.]
A deleted number featuring Jimmy Durante and Polly Moran, a spoof of "Shuffle Off to Buffalo" from 42nd Street (1933) entitled "Fly Away to Ioway", wound up on the cutting-room floor, but footage from this deleted number does survive.
Skits and musical numbers featuring Johnny Weissmuller, Zasu Pitts, Thelma Todd, Jackie Cooper, and Max Baer were deleted before release.
The last film at MGM for The Three Stooges. They would move to Columbia Pictures for the remainder of their careers.
Director Allan Dwan had just returned to Hollywood after three years living and working in England when he was invited to the MGM lot to watch the rough cut of "Hollywood Party." After watching what he later described as "thousands of feet of film, all disconnected stuff," Dwan was asked by E.J. Mannix, Louis B. Mayer's assistant, what he thought of it. Dwan said, "It's a nightmare." Mayer immediately seized upon Dwan's comment and decided to make the main part of the film Jimmy Durante's dream. Dwan shot the beginning and ending framing sequences showing Durante falling asleep while waiting for his wife to get dressed for the party, and cast Durante's real-life wife as his wife in the film. Dwan worked "two or three days" on the project and got "a nice fat check." Though he wasn't credited, working on "Hollywood Party" helped him re-establish his reputation in Hollywood, where he'd been forgotten during the three years he'd spent in England.
