The Muppets (2011)

Revealing mistake: During the opening musical number, right before Gary joins the large group of people for the dance, he accidentally kicks Walter out of frame. Watch closely though. His foot comes nowhere near Walter when he supposedly "kicks" him.

Continuity mistake: During the opening song, as Gary is dancing with the crowd, right before the chorus of the song kicks in, Gary spins around, with his hand to his nose like he's about to sneeze. During the first shot from the front, he puts his hand up to his nose, and begins to turn in a clockwise direction. He turns about 15° as the camera cuts to the next shot, and he has suddenly turned a complete 180° instantly between shots, and is facing the opposite direction.

Revealing mistake: During the opening musical number, after the baker says "Life's a piece of pie" and Gary is seen grabbing a plate with a piece of pie on it and tossing it over his head, watch closely. It becomes obvious that this is a fake piece of pie that is attached to the plate. Similarly, right before that, he grabs a cake out of another baker's hand and gives it to Walter, and you can see he is pressing his fingers into the "frosting", yet he leaves no marks, nor has any frosting residue on his fingers, revealing that was also a prop.

Trivia: HIDDEN MICKEY: At the end, fireworks go and 3 go into the shape of Micky Mouse.

Trivia: Frank Oz, the former voice of Miss Piggy and Fozzie, chose not to be a part of the film, after being dissatisfied with early drafts of the script. He later stated that he enjoyed the finished film for the most part, and that it didn't contain elements he had earlier objected to. (Though he commented that he didn't enjoy the "Disney Process" that went into the production of the film, and he felt that the film was slightly "too safe", though he enjoyed it overall).

Trivia: Due to pacing reasons, the backstory of the villain Tex Richman had to be cut. As originally conceived, when he was a child, his parents hired the Muppets as entertainment for one of his birthdays. However, during their routine, he discovered to his horror that he simply didn't have the ability to laugh like all of the other children, making him feel different from everyone else, and causing him to become an outcast when other children began making fun of his inability to laugh. He blames the Muppets for revealing this part of his personality to the world, and causing him to be ostracized as a child. This explains why he says the words "maniacal laugh", as he simply cannot really laugh. This also would prove that the Muppets eventually "saved" him during the credits scene where Gonzo accidentally hits him with a bowling ball, causing him minor head trauma that finally makes him able to laugh.

Fozzie Bear: Wow, that was such an expensive looking explosion! I can't believe we had that in the budget.

Statler: Is this movie in 3-D?
Waldorf: Nope! The Muppets are as one-dimensional as they've always been!

Veronica: I'm gonna shoot straight: you guys aren't famous anymore.
Fozzie Bear: Yeesh. I wish she'd shot a little more curvy.

Question: What did Richman hate about the Muppets?
