1. Leonardo DiCaprio tried to make fun of his character with the line “I will just wait here”, when in fact this line was not originally scripted. James Cameron said that the line was “Too funny” to ignore it. 2. When Jack (Leonardo DiCaprio) is preparing to draw Rose (Kate Winslet), he tells her to “Over on the bed… the couch.” The line was scripted “Over on that couch”, but DiCaprio made an honest mistake and James Cameron liked it so much he kept it in. 3. When Leonardo DiCaprio’s character Calvin Candie smashes the palm of his hand on the dinner table, the actor broke a glass under his hand and really began to bleed. DiCaprio ignored it, stayed in character, and continued with the scene.
"It’s my first time here. I wanted to come to - you know you don’t go to Comic Con without going down on the floor and seeing it all, and so the way I came up with doing that was Spider-Man." - Daniel Radcliffe at the 2014 SDCC
