10 Insane Changes Movie Sequels Made
8. It's Randomly A Spy Movie - Pitch Perfect 3
The first two Pitch Perfect movies delivered exactly what everybody expected - frothy, silly musical comedies centered around a quirky cast of a cappella singers.
But in a wildly unexpected break from the formula, Pitch Perfect 3 took a sharp left-turn into spy comedy caper territory for a large chunk of its runtime.
The musical elements remain, yes, but the story is considerably more outlandish than its predecessors, with the Bellas eventually being reinvented as quasi-secret agents who face off against a mustache-twirling megalomaniacal villain - Fat Amy's (Rebel Wilson) criminal father, Fergus (John Lithgow).
It even culminates in an epic explosion on a boat, which is surely the last thing anybody expected to see in a Pitch Perfect movie of all things.
One suspects the filmmakers wanted to make fun of increasingly, desperately ridiculous sequels, but without much in the way of accompanying wit or humour it just fell embarrassingly flat.
