The Cat in the Hat

Sally and Conrad are two bored kids whose life is turned up-side-down when a talking cat comes to visit them.

Dr. Seuss' The Cat in the Hat is a 2003 American live-action film, based on the 1957 book, produced by Universal Studios, DreamWorks Pictures, and Imagine Entertainment. It was produced by Brian Grazer and directed by Bo Welch; it starred Mike Myers in the title role of the Cat in the Hat, and Dakota Fanning as Sally. Sally's brother, who is not named in the book, is known in this version as "Conrad" and played by Spencer Breslin.
The movie starts with an inside look of Joan's (played by Kelly Preston) job at Hank Humberfloob's Real Estate agency, where the employees there are forced to clean their hands constantly either with a sink or a Hand Sanitizer. When Joan is called back to work, she gets a sleepy babysitter to babysit her kids, Conrad (played by Spencer Breslin) and Sally (played by Dakota Fanning). Conrad, a 8-year-old boy has 2 problems: He is constantly doing the exact opposite of what he's supposed to do and causing trouble, and Sally, Conrad's 7-year-old little sister who tries to stop Conrad's trouble making. Their next door neighboor, Lawrence Quinn or Larry as Conrad always calls him (played by Alec Baldwin) threatens to marry Joan, and send Conrad away for an 8-hour drive to military school. When Joan leaves, their babysitter, Mrs Quann (played by Amy Hill), invites the children to sit with her in the living room and watch television, and then falls asleep. Not long after, it starts to rain and storm outside and the children get bored. But then there is a thud somewhere in the house, and as the children go investigate, the Cat in the Hat (played and voiced by Mike Myers) appears. After The Cat puts Mrs Quann in the closet, the Fish starts arguing about him being here. The Cat ignores the Fish (even insulting it, saying "Come on, kids, are you gonna listen to him!? He drinks where he pees!") and then convinces Conrad and Sally to sign a contract which will allow them to have all the fun they want, and will stop anything bad happening. The fun begins with the Cat standing in front of a window and singing "I know it is wet and the sun is not sunny. But we can have lots of good fun that is funny. It's fun to have fun but you got to know how." He then magically conjures up a rodeo and a carnival, and then stands on a ball holding up several household items, including a rake, cake, several books, the fish's bowl, and a fan. Afterwards, they jump on the couch (after the Cat had mechanically retrofitted it.) When they make cupcakes out of hot dogs, eggs, ketchup, and a fire extinguisher, the cupcakes explode causing a large mess. The Cat tries to clean up the mess with Joan's dress, much to the horror of Conrad and Sally. The cat then brings in a large red crate, opens it, and releases Thing 1 and Thing 2. Conrad is eager to open the crate. The Cat explains that the crate is a transport to his own world, and warns him not to open it and puts a lock on the crate. The cat then hands Joan's dress to Things 1 and 2, who fling the mess off the dress and onto the couch. The things then go to work attempting to clean the couch, but end up flinging the spots all over the living room. They then start running around and creating even bigger messes, including throwing ceramic plates across the house and breaking a ceiling light. During the chaos, Conrad picks the lock on the crate, which then scurries off and attaches itself to Nevins the dog's collar. The Things throw Nevins out the window, and he runs off. Sally fusses over the state of the house, but The Cat warns them that they have more important things to worry about: if they don't put the lock back on the crate, they'll be in the middle of "The mother of all messes". The trio puts the babysitter on the crate, to buy some time, and chase after Nevins. Meanwhile, Larry is revealed to be a disgusting, unemployed slob. He then sees Nevins running through the street and seizes the opportunity to try to frame Conrad, and just as the TV he is watching is being reposessed. They chase him towards a birthday party, and the Cat gets whacked by a strong kid and blanks out, imagining himself swinging, and wearing a dress. Larry grabs Nevins, and heads for Joan's office. Conrad, Sally, and the Cat manage to get Nevins back. While The Things distract Joan and Larry, the trio get back home, unaware that the babysitter has fallen off the crate to answer a phone call from Joan and that all terror is breaking loose as the crate erupts. When Conrad, Sally and Larry first enter, the house looks spotless. But when the cat reappears at the doorway, Larry starts sneezing and stumbles backwards, only to have the floor rip out from under him as if it were paper and send him falling from a massive high cliff into the Cat's world. The children gasp at what has become of the house After a walk on the suspended in mid air front hall carpet and a thrilling ride on Ms Kwan down a large "water slide" ride flowing with pink stuff, they find the crate, now with a big tornado spinning on top of it that is sucking up everything nearby. Conrad eventually manages to put the lock back on the crate, causing the distorted house to straighten itself, but then it collapses, leaving wreckage everywhere. They send the Cat out, but he comes back with Thing 1 and Thing 2 and a cleaning machine called the Dynamic Industrial Renovating Tractormajigger. They clean up the mess, and the house is clean and back together. The Cat leaves, just in time for Joan to come home. Ms Kwan wakes up and tells Joan that the children were "angels." But then Larry Quinn barges in, covered from head to toe with purple slime and starts telling Joan about the mess and the Seussian world. She sends him away, and things go back to normal. The party goes as scheduled and the kids are told that there purple frosted cupcakes are a "huge hit." The camera then zooms out to reveal that The Cat was telling the story, and during the credits it's revealed that Annville is underneath the Universe.
