39 Utterly Random Movie Facts You Didn’t Need To Know, But Here They Are Anyway

We all have our favorite movies, but even though we’ve seen them a million times there are still little details we miss, or facts we wouldn’t know unless we were on set. Luck for you, I’ve tracked down some of these fun movie facts and I’ll share them with you now, so you can look super smart the next time you’re watching one of these films with someone else.

1. The slow motion sound effect your hear in Dredd was a Justin Bieber song that had been slowed down 800 times.

2. The sound of the velociraptors communicating with each other in Jurassic Park is actually the sound of tortoises mating.

3. In Django Unchained, there’s a scene where Leo DiCaprio smashes a glass in a fit of rage, causing his hand to bleed. This was an accident, but Tarantino kept it in the movie.

4. The stunt double for Daniel Radcliffe was paralyzed in the last Harry Potter movie, so Daniel created a fundraiser to pay for his college education.

5. The voice of Boo from Monsters, Inc., Mary Gibbs, was just a toddler during production. The crew couldn’t get her to sit still and read her lines, so they had her play in the studio while following her around with a mic.
