This was the first major Muppet project after the death of creator Jim Henson. Henson had performed Kermit and the role was now being handed down to Steve Whitmire. According to Whitmire he was incredibly nervous about taking over such an iconic character. The night before he had to go record Kermit's songs for the movie, he had a dream where he met Henson in a hotel lobby and told him how unsure he was. In the dream, Henson reassured Whitmire that the feeling would pass. After waking up, Whitmire was confident and able to do the part.
SERIES TRADEMARK: At the conclusion of the song "One More Sleep", Kermit is seen standing alone in the street and a shooting star can been seen streaking across the sky. In many (in not all) of the Muppet movies, a shooting star goes across the sky at some point when Kermit is on.
The movie is dedicated to the memory of Jim Henson and Richard Hunt. Henson, of course, was the creator of the Muppets. Hunt was one of the Muppet voice performers, perhaps best known as the voice of the character Scooter.
The song "When Love Is Gone" was originally dropped from the theatrical release because Disney thought it would be too sad for young children. This led to an obvious edit in the scene it's supposed to be in and may cause some confusion to Scrooge, Gonzo & Rizzo's reactions. The scene was restored in the VHS and laser discs releases. However, it isn't used in TV airings of the movie and the first DVD release. It's available on the 10th anniversary edition DVD, but only if on full screen presentation.
There are two more songs that are on the soundtrack but aren't in the movie at all. One is "Room in Your Heart", sung by Dr. Honeydew and Beaker as the charity workers. The other is "Chairman of the Board", sung by Sam the Eagle as Scrooge's headmaster. Both were recorded, but dropped from the script before filming started to help the flow of the story.
