10 Best Movie Twists You Genuinely Never Saw Coming

10. Hannah Is Cal's Daughter - Crazy, Stupid, Love

The inherent genius of the big plot twist in Crazy, Stupid, Love is that nobody really went into the star-studded rom-com expecting there to be a rug-pull at all.

Steve Carell stars as Cal, a recently separated man who has a chance encounter with serial womaniser Jacob (Ryan Gosling), who vows to coach him in the art of picking up women.

All the while, Jacob has found himself smitten with a woman, Hannah (Emma Stone), enough that he begins to question his promiscuous lifestyle and consider a possible monogamous future with her.

The two stories seem basically unrelated until, late in the film, Hannah brings Jacob home to meet her parents, where we learn that Hannah is in fact Cal's daughter.

Hilarity, disbelief, and eventually anger follow, as Cal struggles to reconcile that the womaniser he's been hanging out with is dating his own daughter.

A fight even breaks out at the gathering with the police being called, but Cal eventually gives his blessing for Jacob and Hannah's relationship.

If you saw this movie in a packed cinema on opening weekend, you'll surely remember the visceral, uproarious laughter from the assembled masses. Rom-coms rarely, if ever, produce this sort of audience response, and certainly not because of an ingeniously deployed plot twist.
