SERIES TRADEMARK: At the conclusion of the song "One More Sleep", Bob (Kermit the Frog) is seen standing alone in the street and a shooting star can been seen streaking across the sky. In many (not all) of the Muppet movies, a shooting star goes across the sky at some point when Kermit is on.
This was the first major Muppet project after the death of creator Jim Henson. Henson had performed Kermit the Frog 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.
Jacob and Robert Marley tell Scrooge to leave comedy to the bears. Statler and Waldorf, who play the Marley brothers, are known for constantly heckling Fozzie Bear for his poor comedy throughout The Muppets productions.
The song "When Love Is Gone", as sung by Belle, was recorded and filmed, but then dropped from the theatrical release (over the objections of director Brian Henson) at the request of Disney chairman Jeffrey Katzenberg on the grounds that it would be too sad for young children. This last-minute decision resulted in a jarring and obvious edit in the scene where it was removed, and leaves some confusion to Scrooge, Gonzo & Rizzo's reactions. The scene was restored in the VHS and laserdisc releases, but it isn't used in TV airings of the movie or the first DVD release.
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.
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.
