Don't ask LEONARDO DICAPRIO if Jack could have fit on that door with Rose at the end of "Titanic", because he doesn't want to talk about it. It came up during a cast interview for "Once Upon a Time in Hollywood", and even BRAD PITT got into the action, saying, quote, "Could you have squeezed in there?  You could have, couldn't you?"  And Leo gave him a quick "No comment." Then MARGOT ROBBIE asked him if he brought up the idea of making the door smaller while they were filming . . . and he replied, quote, "Like I said, I have no comment." https://www.instagram.com/p/Bz8-Q-THi4z/?utm_source=ig_embed SOURCE: MTV NEWS
