3. Claire Danes and Leonardo DiCaprio “Romeo and Juliet”
Danes and DiCaprio played the star-crossed lovers in the modern adaptation, but allegedly did not feel as warmly toward each other off camera. Rumor has it that Danes didn’t like DiCaprio goofing off at work, and avoided him whenever possible — which was any time they weren’t sharing a scene.
4. Julia Roberts and Nick Nolte “I Love Trouble”
Nolte and Roberts played love interests on-screen but couldn’t stand each other in real life, preferring to play off of stand-ins than one another. Roberts allegedly hated Nolte’s “machismo” and insulted her co-star at every chance she could.
