Professor Ned Brainard (Fred MacMurray) needs money for Medfield College. The Pentagon has made flubber top secret. He's running into red tape over the payment. The IRS is after him despite not receiving any actual money. Mr. Hawk is eager to see him fail. The college needs $350k by the first of the month to pay Hawk back. Ned's solution is to invent weather controlling flubbergas. Betsy's not impressed. Despite his objection, Betsy invites Shelby. To Betsy's horror, Shelby invites Ned's old flame Desiree de la Roche/Mary Lee Spooner.Hawk is a solid villain. The IRS guy is more annoying than funny. Then the money issue gets overused. I have a problem with Betsy. She's made out to be a flighty jealous money-grubber. The movie still has the wacky invention and the socially tone-deaf professor but his dismissal of her isn't that nice either. Their relationship is problematic and seems to be built on rickety scaffolding. It's meant to be funny like a sitcom. The movie really needs to start the couple with love before it injects all the obstacles. That really turns me off.

Robert Stevenson returned to direct this sequel to "The Absent-Minded Professor" which also sees Fred MacMurray return as Medfield college professor Brainard, who is working on a new invention derived from flubber called flubbergas, which he hopes will make the school a fortune, since the Pentagon put a hold on flubber itself for military use, and he has been sent a big tax bill by the IRS. Keenan Wynn returns as crooked businessman Alonzo Hawk, who also wants flubbergas for his own profit, while Brainard uses it to affect the weather and help the school football team. Equally silly sequel, only more so, and as a result is a slight step-down from the first. For kids mostly.

this sequel to The Absent Minded Professor is actually a better movie.i found it funnier,more entertaining and it had a better story.the character were expanded a bit more,which makes sense,since it is a sequel.unlike Professor,this one doesn't have any slow or boring moments.it's much better paced.i like the fact that the wife had more to do in this one.the movie is just as silly,but it's meant to be,and if you keep that in mind going in,you'll probably enjoy it more.it's not high art or anything,but it will keep you entertained for 102 minutes or so.and it's fun for the whole family.my vote for The Son of Flubber:6.5/10

Yeah, readers, you'll want to vote 10 after seeing this!!!!!Disney made a sequel to the "Absent-Minded Professor" movie in 1963 called "Son of Flubber," where our professor is making another experiment! If I remember correctly, it probably had to do with loud sounds; I remember the "Auld Lang Syne Insurance" window breaking, then someone dotted one of the "I"s thereafter even though the glass was broken!!!!!I've seen this in B&W on an old VHS in 1996, and in a colorized form on the Old Disney Channel in 2000 or so.Come to think of it, I remember that instead of basketball, football was involved in this movie! Someone kicks the football high out of the stadium ("It looks like it's going into orbit!!!!!") and after the last conversation, we see a satellite, then that football orbiting the earth before we see "The End, A Walt Disney Production" over the Earth."Son of Flubber" - now that's nice!!!!!10/10
