Maybe one of the reasons that the A Muppet Christmas Carol works so well as an adaptation is that the Muppets are particularly well-suited for capturing Dickens' comedy. A movie can't capture all the wordplay and wry satire of the book's prose, but a Muppet adaptation comes closer than maybe any other version could, because the Muppets love wordplay and satire, so even if the humor isn't quite what Dickens would do, it's not against the spirit of the book. Muppets are broad, clearly-defined character types--much like what Dickens is known for--so casting Muppets as Dickens characters is a surprisingly natural fit. And the Muppets also have an earnestness that lets them portray the sweeter side of the story. It's a very deft match between the two properties--they're just slightly different flavors of the same storytelling spirit.
(And, honestly, I can't imagine any actor capturing the warmth and jolliness of The Ghost of Christmas Present better than "giant custom-made Muppet-suit" could.)
i love it when a film has its guts out. when the practical effects are visceral and slimy and slightly janky and clearly made by human hands, when green screen is used as a canvas for art rather than a substitute for reality, when the sets look like theatre pieces, when the lighting is unashamedly unrealistic because fuck it - it comes from the same place as the music, when the acting is messy and unfettered by irony, when you can feel the presence of the crew just offscreen pouring in months of hard work and late nights and sweat and love. when a film stops trying to be realistic and lets itself be raw and weird and INTERESTING
edit: glad people are enjoying this post! I originally wrote it about Bunny and the Bull (2009), which is my favourite film ever and you can watch it for free on youtube and in this google drive. enjoy! :)
Costumer Polly Smith literally had two months from her last day on the series Dinosaurs to the start of shooting of A Muppet Christmas Carol. She had to dress every Muppet and human in the film. "I was flying by the seat of my pants that whole time," she remembered. "I always had something in my hands so if I was talking to anybody, I was also rolling in the edge of a cravat. Or, I actually took handfuls of coats home at night because I had a really good buttonholer on my sewing machine at home. I just couldn't relax; there just wasn't time to relax!" And the first day of production featured the biggest scene of the film in the square.
Dave Goelz added, "I would add to that the costumes that the Muppets have worn meant that they are better dressed than we are. They always have been at. The Muppets have real pockets in their costumes. They have real lining in their jackets. There's so much fidelity."
