Also, gossip about a fall out between the two was doing the rounds. Although, Smith has laughed off the reports of a tiff between them, he confesses that it was hard to direct Willis. "Bruce Willis is probably the most intimidating actor I've ever worked with. I find him - and I don't mean this in an insulting way – undirectable," the Daily Express quoted Smith, as saying.
He added: "He has all sorts of range, but what he's predominantly known for is playing the guy who holds his gun down by his side and saves people. How do you tell Bruce Willis to be Bruce Willis?"
