The Cat in the Hat is a 2003 film adaptation to the book of the same name, with the titular character portrayed by Mike Myers. It was not well received by critics and fans, and especially the Geisel Estate, who effectively stopped production of any future live action adaptations.
The film contains examples of:
Adaptation Expansion: Well, there's a dog, Mom's boss demanding that her house be spotlessly clean for a party that night, an evil neighbor (Alec Baldwin) trying to woo Mom and get the boy shipped off to miliary school, the Cat's universe (likely the world of Who) intruding on this one, etc.
Arson, Murder, and Jaywalking: "He [Thing 2] says, feel free to call him 'Thing A' if you like. He will also accept 'Super Thing', 'Thing King', 'Kid Dynamite', 'Chocolate Thun-da!'...or 'Ben'."
Bad Boss: Played for laughs with Mr. Humberfloob, Mom's boss, who fires someone for shaking hands with him (and the employees' reactions imply that he's done this before). Not to mention he frequently screams "FIIIIRRRRREEE-D" at them. Even in this story's universe, it's kind of strange that he has any employees.
Batman Gambit: Part of The Cat's plan for the day hinged on Conrad unlocking and opening the crate. The Cat, knowing Conrad to be a serial rule-breaker, specifically told Conrad not to open the crate knowing full well that he'd then be compelled to open it.
"Why do you think I made it a rule not to open the crate? I knew you couldn't resist."
Bitch in Sheep's Clothing: Lawrence sets himself up as an ideal, thin, real estate agent and boyfriend, but in reality, he's an unemployed slob with a big gut who just wants to marry Joan for money (because he's about to lose his house). For the first part of the film, only Conrad can see him for what he really is.
Crazy-Prepared: Everything that happened in the film was planned in advance by the Cat, including Nevins being taken by Lawrence. Of course, chopping off his own tail was purely an accident.
Deus ex Machina: At the end of the film, the house has been destroyed, the Cat has left, and Conrad and Sally are left sitting on the stairs waiting for their mother to come home and chastise them. The door opens...and lo and behold, it's the Cat again, with a machine fully capable of repairing the entire house and undoing all the damage caused throughout the film (which it then proceeds to do).
Disowned Adaptation: The Geisel estate really wishes that people would forget about this film, as shown by the upcoming Animated Adaptation and a recent exhibition on Seuss completely ignoring the film's existence.
As mentioned above, Humberfloob fires an employee on the spot for shaking his hand.
It's strongly implied Humberfloob is obsessive-compulsive about cleanliness, which would explain this seemingly extreme reaction.
Sally has ended at least two of her friendships for things such as wanting to be Head Chef when making cupcakes, and talking back to her. And in that case she ordered the other girl to never speak to her again.
Double Entendre: The live-action adaptation was PACKED with them. One of the most prominent being The Cat saying "Dirty ho!" as he throws away a garden hoe.
Everybody Owns A Ford: A Ford Focus hatchback in Egg Yolk Yellow or a decidedly non-stock lime green, with equally non-stock wheel spats that spoil the car's lines.
Franchise Killer: It did well at the box office, but good luck finding someone who likes it. It was bad enough that Dr. Seuss's estate no longer authorizes live-action film adaptations of his books. CGI films are okay though and all adaptations since then have been trying to avoid the mistake this movie made.
Fun with Acronyms: Super Luxurious Omnidirectional Whatchamajigger (S.L.O.W.), formerly the Super Hydraulic Instanteous Transporter (S.H.I.T.).
There was this cat I knew, back home where I was bred, He never listened to a single thing his mother said, He never used the litterbox, he made a mess in the hall, That's why they sent him to a vet and they cut off his b- *pauses* ...bo...bo...bo...BOY!
There's even a deleted verse with the words "Kill the bug up her aaa..." 'Nuff said.
An extreme example is when the Cat's hat is squashed and crooked, but then he looks at a picture of Sally and Conrad's apparently attractive mother, and his hat SHOOTS UP with an audible *BOING* sound!! How did THAT get past?!
In certain scenes the Cat's voice sounds somewhat similar to Shrek (another Myers character).
I Warned You: After the house is destroyed, the Fish begins one of these:
The Fish: "Now this may not be the time for 'I told you so'... (part of the ceiling falls) ...Like I said, not the time!"
Large Ham: Mr. Humberfloob says, "YOU'RE FIIIRRREEEDDD!!!" Also, the Cat arguably falls under this.
Left the Background Music On: In one scene, Sally, Conrad and the Cat are trying to creep up on their dog, who has run off with the movie's MacGuffin, without startling him. Their movements are accompanied by a set of increasingly tense string chords...until Sally and Conrad turn round to see the Cat playing the chords on his whiskers. Actually justified by the Cat:
Medium Awareness / No Fourth Wall: The film is full of these types of jokes, to the point where it almost seems more like a parody of Dr. Seuss than an actual adaptation of his work.
Playing with Syringes: Conversed. One of the suggested treatments for Conrad being a "rule-breaker" and Sally being a "control freak" on the Cat's Phunometer is "a series of painful injections in your abdomen and kneecap."
Screwed by the Lawyers: Mike Myers was legally forced to do the movie after he got sued by Universal over a proposed Sprockets film adaptation. Part of the legal settlement he had with them was that he was required to do a different movie for them. After Tim Allen dropped out of this movie, Myers ultimately stepped in just to get Universal out of his hair.
Shout-Out: During the "dirty ho" scene, the name on the pug's doghouse is Frank.
Terrified of Germs: Hank Humberfloob. He forces his employees to wash their hands constantly, and when a new recruit shakes his hand, he fires him on the spot before scrubbing his hands with hand sanitizer.
