Well, Austin was once filming a scene outdoors. There were a lot of bugs around. As he was delivering his lines, a big, fat bug flew right into his mouth. He spat it out immediately and then started laughing so hard. The whole crew was in stitches. He then joked that it was nature's way of trying to tell him to stop talking so much during the scene.
Sure. Austin Butler was at an awards show. He was wearing a really fancy suit, but as he was walking up the stairs to the stage, his shoelace got caught on a step. He nearly tripped but managed to turn it into a little dance move. Everyone in the audience started laughing and clapping. It was a bit embarrassing at first, but he ended up making it a memorable moment.
