I think the misconception is that a 1951 film renewed in 1980 is a valid renewal. Regardless of when it was released, at about 1:20 the film clearly shows a valid notice dated 1951.

I was sent this notice from barry.goold@warnerbros.com of Warner Bros. Entertainment:

"Jack and the Beanstalk was registered and renewed with the US Copyright Office, although there is a common misconception that it was not renewed. The renewal is at RE 136-766."

A jolly good version of an old tale.
Suitable for all ages.

Not old enough to have seen it in a theater but definitely remember it from TV as a kid.

A little borrowing from Wiz of OZ as far as B&W reality and Color fantasy with the added bit of the color being added bit by bit in the transition scene.

Skipped through the so so music numbers, but an entertaining bit of A&C.

i like movies with tights. what the sneck did i just watch? my beans never grew. there needs to be more tights. centipede buffet with flying cactus eyes. the movie was okay. where are all the munchkins and the lion? that beanstalk grewfast. id rather read the book. pole vaulting panda bears. cling onto velcro walls with xerox shoes.

I remember when I saw this film obviously many years ago, these actors succeded Laurel & Hardy.

I enjoy anything this duo does, this is one of their later films but its still entertaining

Okay they get a bit strange now and then but they are a humerous and entertainig team in this wizard of oz take-off using jack and the beanstalk.
