10 Even More Movie Mistakes Directors Refused To Fix Because The Acting Was Too Good

10. Gyllenhaal Vs. Mirror - Nightcrawler

Sadly, 2014's Nightcrawler did not have Jake Gyllenhaal wear blue makeup and grow a tail in order to play the famous X-Man.

Instead, he portrays a photographer who gets involved in more and more dangerous acts whilst trying to snag the perfect scoop to sell to the papers.

Gyllenhaal's character gets more and more unhinged as the plot goes on, to the point where he smashes up a mirror in frustration. Sadly for the actor, he went a little too method for his own good.

Similarly to Channing Tatum in Foxcatcher, Jakey G really did crack the mirror by mistake. Only he smashed it with his hand instead of his head.

Whilst not in any danger of getting a concussion, Gyllenhaal did need multiple stitches after the accident and his hand was in a bad way for the rest of the shoot. However, this was clearly worth it for director Dan Gilroy, who used this take in the final cut.

Nightcrawler was very well-received when it first came out, including getting an Oscar nomination for Best Original Screenplay. Crazy to think then how different things could have gone if this moment were any worse.
