Have there been any actor, actress, or director fails that ended up making the movie even better?

In Captain America: The First Avenger whilst Chris Evans comes out of the gadget looking buff after the remarkable soldier serum is injected in him, actress Hayley Atwell touches him on the percent. This was not inside the script. Atwell couldn’t assist herself. The director decided to maintain it inside the movie because it became a genuine unconscious response by Atwell. You can see that is by using the look of marvel from the actress playing the nurse inside the background.

In Guardians of the Galaxy Vol.1, while Chris Pratt is making an attempt to hand the Orb containing the electricity stone to The Collector, he finally ends up dropping it before quickly catching it. This become absolutely unintentional. James Gunn decided to preserve it in the film as it turned into pretty humorous. In Indiana Jones and the Raiders of the Lost Ark, in which Harrison Ford shoots the lone swordsman rather than preventing him, it became truely now not in the script. During this time inside the taking pictures, Ford suffered from dysentery, so he may want to handiest shoot for 10 minute increments. They have been almost out of time, and that they needed to shoot the scene. So Spielberg decided to simply have Ford shoot the swordsman rather. This made it an iconic scene.
*I simply idea about this one and introduced it to the listing, as I am a big fan of this movie, and it might be pure injustice if I didn’t include it. The scene on the give up of Die Hard in which Hans Gruber (performed to perfection through Alan Rickman) fell to his loss of life, the response you spot on his face is real. To get the realism in expression on Rickman’s face, the director and stunt coordinator told Rickman that they would drop him at the depend of 3, however they dropped him on 2 while he changed into now not awaiting it. This scene is one of the maximum iconic villain demise scenes within the movie history. Yes this is a fail due to the fact they did not communicate with Rickman about this.
