This is one of the most notorious cases of a kiss being refused in the history of Hollywood. Julia Roberts and Nick Nolte were cast as a pair of star-crossed lovers in 'I Love Trouble,' but the only thing they were crossing on set was swords. They got off on a bad foot on day one, and their relationship deteriorated from there. In the years since, Nolte has said that Roberts is 'not a nice person,' whereas she describes him as 'completely disgusting.'
Given that the two lead actors in the film openly hated each other, the question of persuading them to kiss wasn't an easy one to solve. Eventually, they did - in the most limp, awkward, and unconvincing way imaginable. The scene, like the film, was a complete flop. You can't make a romantic drama when there's palpably no romance between the two people who are supposed to be in love.
