The Monkey's Uncle (1965)

Slow and formulaic, it does at least have an amusing eventual pay-off. 'The Monkey’s Uncle' is a sequel that never needed to be made. It isn't an awful film at all but struggles in a similar way as 'The Misadventures of Merlin Jones' does, just without the promising beginning. The premise is dull, there is minor intrigue in the Darius Green III (Arthur O'Connell) plot but everything that builds up to it is uninteresting and mostly predictable. Tommy Kirk (Merlin) and Annette Funicello (Jennifer) are solid, but the performance of Leon Ames (Holmsby) comes across more sillier than in the 1964 production. Disney continue to be iffy with their live-action sequels.
