One of the most famous ones is Julia Roberts and Nick Nolte:
Julia Roberts called Nick Nolte “disgusting” and Nolte responded by saying that Roberts was “not a nice person.”
They clashed so much on the set that the director had to use body doubles for the love scenes, though, the director did get them to do a kiss on screen.
Cate Blanchett and Brad Pitt
Brad initially refused to do a love scene with Cate to appease Angelina, Brad’s girlfriend at the time. The director David Fincher stepped in and eventually got him to do the scene.
Ryan Gosling and Rachel McAdams
Gosling hated McAdams so much he demanded that she be fired from the movie because they “lacked chemistry.” Director Nick Cassavetes refused to fire her and forced them to work it out. Ironically, the two ended up dating for several years after the movie.
Harrison Ford and Sean Young
These two could not stand each other. It got so bad that their love scenes were described by the crew as “hate scenes.”
Tom Cruise and Thandie Newton
On Mission Impossible 2, Thandie Newton was not a fan of Cruise’s kissing style and found it very off-putting.
Speaking to Elle, Thandie described her reluctance for the scenes: “Kissing Tom Cruise was slightly icky and sort of wet.”
