Even with a good collection of familiar faces from British comedy and a serviceable plot at its core, this film is simply awful. Jim Dale, an original cast member of "Carry On," plays the lead character who’s dispatched by Ferdinand and Isabella to retrieve gold from the New World without offering tribute to the greedy “Sultan,” portrayed by Rick Mayall. Knowing about this scheme, a thinly veiled young woman named “Fatima” (Sara Crowe) is sent to join the crew with the intention of derailing their plans—but will she be able to resist the captain’s allure? Furthermore, can this sailor maintain control of his shipmates and himself as the voyage leaves them feeling hungry, dehydrated, restless, and lustful? Perhaps things will improve upon reaching the New World, since the local population is likely to be somewhat simple-minded. Aside from a brief, silly verbal game between Dale and Richard Wilson’s stoic character, there's almost nothing fresh or amusing about this adventure filled with suggestive jokes and tired stereotypes. It doesn't help that the studio sets look like they belong in the 1930s—maybe the actual jungle wasn’t available for filming—and the writing feels forced and uninspired most of the time. These comedies were best when their humor was cheeky, sure, but it often had a bit more cleverness than what's on display here; this writing is childish, exemplified by an out-of-sorts Julian Clary and a completely miscast Bernard Cribbins who should have known better. The formula was rightfully discontinued years ago and should’ve remained buried as a footnote in British film history. Instead, this unnecessary addition to the original films helps no one and makes even your average Christmas pantomime seem like award-winning literature. It's a final blow to the “Carry On” legacy, really.
