KJ Apa’s ice punch as Archie Andrews in 'Riverdale' was a little more forceful that expected. During an interview with TVLine in 2017, the actor revealed that he got a little too into character.

Quentin Tarantino’s western film had a scripted scene where Leonardo DiCaprio was supposed to slam his hand on a table as his unscrupulous character Monsieur. The actor ran through the scene several times in order to achieve the perfect scene, which only happened when he accidentally slammed his hand into glass and cut it.

It was very intense. He required stitches."

The extreme pain Viggo Mortensen's character Aragorn experiences after hitting his helmet was real and unplanned.

He was letting that pain feed and drive his performance, which is pretty amazing."

The famous scene where Edward Norton's character punches Brad Pitt's character in the ear was also not in the original script.
