It's been years since the love triangle between Harry, Hermione, and Ron was the most pressing news of the day for the tween set, but, it's now been revealed, there was a point when even the Harry Potter actors could hardly contain their excitement.

According to a new Buzzfeed roundup of "mind-blowing" movie facts, Rupert Grint, who played lovable pal Ron Weasley in the blockbuster franchise based on J.K. Rowling's books, had to be kicked off the set of the movie after he was "laughing too much" during a kissing scene between Hermione (Emma Watson) and Harry (Daniel Radcliffe).

The now-24-year-old British actor has since moved on from his magical child star roots and will next play a drug-addicted gangster in a West End revival of Jez Butterworth's Mojo.

In other surprising movie news, it turns out that multiple A-list actors turned down the role of Forrest Gump -- including the likes of Bill Murray, Chevy Chase and John Travolta -- before the iconic part was given to Tom Hanks, who would go on to win the Best Actor Academy Award the following year.
