Adapted from a novel by C.S. Forester, The African Queen stars Humphrey Bogart in his Oscar-winning portrayal of Charlie Aunt -the slovenly, gin-swilling captain of a tramp steamer called The African Queen,which ships supplies to small East African villages during World War I.

Katharine Hepburn plays Rose Sayer, the straight-laced spinster sister of a prim British missionary, Brother Samuel (Robert Morley).

When invading Germans kill the missionary and level the village, Aunt offers to take Rose back to civilisation. She can't tolerate his drinking or bad manners; he isn't crazy about her imperious, judgmental attitude.

However, it does not take long before their passionate dislike turns to love. Together the disparate duo work to ensure their survival on the treacherous waters and devise an ingenious way to destroy a German gunboat.

The African Queen may well be the perfect adventure film, its roller-coaster storyline complemented by the chemistry between its stars. Along with masterful direction by John Huston, the wonderful script makes this a rare treat indeed.
