I hope Universal Pictures will do a live action sequel based off the original sequel The Cat In The Hat Comes Back someday in the future. Since Audrey Geisel died in 2018 there is still hope for a live action sequel. I got an idea for The Cat In The Hat Comes Back live action remake. How about they would make it like Mary Poppins Returns but with a little twist to it. Because the two child stars Dakota Fanning and Spencer Breslin who played Sally and Conrad who are now in their 20s and 30s and Kelly Preston who played their Mom died a few months ago. Alec Baldwin who played Larry is still alive and Mike Myers who played The Cat In The Hat is still alive too. So maybe Larry will come back to the Walden house to get his revenge on Sally and Conrad where Conrad is now married with kids of his own and Sally became an Aunt to Conrad's kids and The Cat will come back to help the family. By the way, I think I know why Audrey Geisel forbidden any future live action movies on Ted’s work because in the live action Cat In The Hat movie with all the subplots and adult humor you can tell that they are running out of ideas for future live action Dr. Seuss adaptations. The Live Action Cat In The Hat movie was a good way to end the live action Dr. Seuss adaptations. Or is it? But who knows when they are going to do another live action Dr. Seuss adaptation. When The Cat In The Hat Comes Back Live Action Remake dose come down the line in the movie making business I bet they will bring back the 2003 cast and do a better job than they did with the first movie. It's been a very long time since the 2003 movie was released and it's about time they would do a sequel. When the live action Cat In The Hat movie get's it's 20th anniversary in 2023 then The Cat In The Hat Comes Back Live Action Remake will happen. 

Here is the plot from the Dr. Seuss book.

The Cat in the Hat Comes Back is a 1958 children's book written and illustrated by Dr. Seuss and published by Random House. In this book, a sequel to The Cat in the Hat (1957), the chaos-causing title character leaves a pink stain in the family bathtub, which spreads around the house as the children try to get rid of it, until the cat unveils a series of increasingly small cats from beneath his hat, the smallest of which resolves the problem. 

Once again, Sally and her brother, Conrad, are being left home alone for the day, but this time, their mother has left them with instructions to clear away a large amount of snow while she is out. However, they are soon interrupted in their work by the arrival of the Cat in the Hat. Sally warns her brother not to talk to the Cat nor to let him come near, reminding him of what happened the last time he came. However, the Cat lets himself into their house to get out of the snow, and Conrad follows him in. When he reaches the bathroom, he finds the Cat eating a cake in the tub with the hot and cold water on. Conrad (who loses his patience) scolds the Cat for his antics. He gets mad, then he tells the Cat there is work to be done and he should not be in the house eating cake like a pig. He clarifies to the Cat that he can be welcome to stay in their house if he helps out with the work. Conrad means the Cat is allowed to stay as long as he helps him and Sally when there is work to be done (and only for work). If not, he should get out of the house. Then Conrad turns off the water and drains out the tub (so the Cat can help him and Sally with the work), only to find that a long pink ring has formed around the sides of the bath tub. The Cat offers to help, but his preliminary attempts to remove the pink spot end in disaster as he only transfers the mess to a succession of one object after another, including their mother's white dress, the wall, their father's pair of $10 shoes, a rug, and their parents' bed. Unsure of how to remove the stain from the bed, the Cat calls on the help of Little Cat A, who lives inside his hat, who lifts his hat to reveal Little Cat B, and then Little Cat C. The three Little Cats go to work, transferring the stain to the television, then a pan, and finally outside with a fan.

Seeing the spot cover the snow, Little Cat C lifts his hat to reveal Little Cats D through G. The seven Little Cats wage war on the snow spots, shooting at pink snowballs with pop guns. This spreads the spots even more, so Little Cat G lifts his hat to reveal Little Cats H through V. But the harder the cats work, the more the spot keeps spreading, until all the snow is pink, so Little Cat V takes off his hat to uncover Little Cats W, X, Y and the microscopic Little Cat Z. Z takes his hat off and unleashes a "Voom", which finally cleans up the spot, clears all the snow from the paths, and puts all of the Little Cats back into the Big Cat's hat. The Cat leaves, with the promise that he and the Little Cats, to A through Z, will return someday if they ever again have problems like "snow spots" (maybe starting the next day for starters if there is still a problem).

The book ends in a burst of flamboyant versification, with the full list of little cats arranged into a metrically perfect rhymed quatrain, reciting the alphabet.
