With Five Weeks in a Balloon, 20th Century-Fox hoped to cash on the success of the studio's earlier Jules Verne adaptation
Journey to the Centre of the Earth (1959). The plot is set in motion when 19th-century explorer Fergusson (Sir
Cedric Hardwicke) volunteers to head a balloon expedition to claim an otherwise unreachable chunk of African territory for the British Empire. Along for the ride are reporter Donald O'Shay (
Red Buttons), absent-minded professor Sir Henry Vining (
Richard Haydn), Vining's assistant Jacques (
Fabian) and schoolmarm Susan Gale (
Barbara Eden). Along the way, the little party acquires another passenger when they rescue native girl Makia (
Barbara Luna) from a slave trader. Their many near-death experiences include a run-in with evil potentate Sheik Ageiba (
Henry Daniell). Other reliable characters on hand include
Peter Lorre,
Herbert Marshall,
Reginald Owen,
Mike Mazurki, and, in a dual role, sneezemaster
Billy Gilbert. Since no one could be expected to take this sort of fare seriously, Five Weeks in a Balloon is played tongue-in-cheek, peppered with such overripe dialogue as "You, sir, are a cad!" and "Kismet! We are doomed!" ~ Hal Erickson, All Movie Guide
