Virtually the entire star stable was thrown into this movie because Paramount was trying to keep from going bankrupt and thought that such a star-laden movie could save the studio from failing. It didn't work since most of the stars couldn't be recognized because of their costumes. Instead, two Mae West movies, She Done Him Wrong (1933) and I'm No Angel (1933) saved the studio from bankruptcy instead.
During the Mad Tea Party, the Hatter asks Alice what day of the month it is and Alice answers that it's the 4th. The Hatter checks his watch and bewails the fact that "it's two days off." When Alice examines the watch, the hands on the dial indicate the date as being a Tuesday in June. In 1933 when this film was made, June 4th fell on a Sunday - two days off from what the Hatter's watch indicates.
Never legally released on any home video format until the 2010 DVD edition, which was prompted by the popularity of Alice in Wonderland (2010) in cinemas. The more famous Alice in Wonderland (1951), already available in several home editions, had an "un-anniversary" DVD repackaging at the same time.
The Mock Turtle, who says he is what mock turtle soup is made from, is a cow in a turtle's shell. This was because mock turtle soup (for those who couldn't afford to have real turtle soup) was generally made from veal.
Although much of the technical crew of the film is left completely uncredited (standard practice at the time), the opening credits sequence is one of the longest up to that time, lasting almost a full three-and-a-half minutes. Its length is due to the fact that practically every character was played by a major star or character actor of the time, and all are listed, one by one.
When Paramount previewed the film in 1933, the original running time was 90 min. However, by the time it was shown to the press, the running time was cut to 77 minutes (many reviews, including the savage one it received in Variety, made a point of how long it seemed at an hour-and-a-quarter). Although it is often reported that Universal Studios cut it to 77 minutes when they bought the television rights in the late 1950s, the film went on general release in 1933 at the shorter length. The film is now legally available on DVD.
The film was one of several theatrical films based on literary classics which were released to US schools in the 1950s and '60s, for showing to children. The others included Heidi (1937) and The Adventures of Huckleberry Finn (1939). They were all released to the schools in heavily cut versions that had a running time of no more than forty-five minutes.
Three cast members in studio records/casting call lists for this movie were not seen in the final print. These were (with their character names): Julie Bishop (Alice's Sister), Harvey Clark (Father William) and Lucien Littlefield (Father William's Son).
