Produced in the wake of the all-star "comedy spectacular" Those Magnificent Men in Their Flying Machines, Fantastic Flying Fools (originally titled Blast-Off, and also released as Those Fantastic Flying Fools) is based very loosely on a Jules Verne novel. A 19th century British newspaper offers a prize to the first scientist who is able to construct and launch a rocket to the moon. Contestants from all over the world compete for the prize, including Those Magnificent Men in Their Flying Machines cast members Terry-Thomas and Gert Frobe. Much of the slapstick is tiresome and derivative, but there is one cute closing gag involving villains Terry-Thomas and Lionel Jeffries and a Siberian chain gang. There's precious little of the spirit of Jules Verne in Fantastic Flying Fools, save for the woodcut illustrations which decorate the opening credits.
