10 Famous Movie Endings That Were Total Accidents
5. The Boston Red Sox Won The World Series Against Everyone's Expectations - Fever Pitch (2005)
The Farrelly brothers' 2005 remake of British sports rom-com Fever Pitch changes the sport from football to baseball, and therefore shifts from following Arsenal's quest to win the League title to the Boston Red Sox's unlikely effort to win the 2004 World Series.
While the film was being shot in 2004, the Red Sox were in the midst of the infamous "Curse of the Bambino," a superstition that the team was cursed because they hadn't won a championship since 1918, shortly before Babe Ruth left them.
And so, with the "curse" seeming unlikely to lift anytime soon, the film was originally written to end in bittersweet fashion, with protagonist Ben (Jimmy Fallon) coming to accept that the Red Sox are a doomed team, while a romantic reconciliation with love interest Lindsey (Drew Barrymore) cushions the blow.
It was a totally reasonable assumption that the Red Sox would lose in the playoffs, but fate intervened and, miraculously, they went on to win the 2004 World Series, breaking the 86-year curse in the process.
Before the Red Sox's winning game against the St. Louis Cardinals, though, the filmmakers recognised the possibility of history being made, and so quickly decided to shoot an additional epilogue sequence during the game itself.
The Farrellys had Fallon and Barrymore attend the game in-character and, once the Red Sox won, instructed them to run onto the pitch to passionately make out while a camera crew captured it.
For a sports-centric rom-com, endings don't come much more feel-good - or serendipitously euphoric - than this.
