Box office The film was the 18th most popular movie at the UK box office in 1969.
Critical The New York Times wrote, "The film evolves as a tongue-in-cheek, campy chase through Senegal's bush country, where it was shot in lovely pastel shades...Mr. Welles, looking like Buddha, swilling whisky, speaking in a pseudo-Cockney accent and perspiring in a white hunter's getup, lazily adds to the lampoon. "It's supposed to pull your leg," Mr. Segal explains to Miss Andress as he sets a trap for their pursuers. "The Southern Star" does just that, even if it isn't funny enough during a good deal of the trek"; The
Los Angeles Times said the film "wisely plays it for laughs" and was "not particularly well made". The
Radio Times noted a "Splendidly photographed African adventure filmed on authentic Senegalese locations, but alas bearing the curse of the international co-production. Underrated editor-turned-director Sidney Hayers tries to pull together the Jules Verne-inspired plot and a cast that verges on the preposterous, headed by George Segal (far too urban for this type of trek), the ravishingly lovely Ursula Andress, and the great Orson Welles, who was obviously in need of the money. Brits, Ian Hendry and Harry Andrews bring some dignity to a romp that isn't sure whether it's comedy or adventure or both, but it looks good nevertheless." ==References==
