10. Joel Schumacher & Val Kilmer/Tommy Lee Jones & Jim Carrey (Batman Forever)Joel Schumacher's 1995 film Batman Forever came at a time when the superhero franchise was at a low ebb, prior to Christopher Nolan revitalising it in the mid 2000s with Batman Begins. There were two on-set feuds throughout filming, in what was a pretty frosty few months on set. Schumacher and the famously hard to work with Val Kilmer clashed hugely, with the latter reportedly insulting crew members and generally being a nuisance. The pair ended up not speaking for two weeks of filming, and the director revealed all about Kilmer's erratic behaviour after the film's release.
He was being irrational and ballistic with the first assistant director, the cameraman, the costume people. He was rude and inappropriate. He was childish and impossible. I was forced to tell him that this would not be tolerated for one more second. Then we had two weeks where he did not speak to me but it was bliss!"Their frosty relationship wasn't the only issue, however. Tommy Lee Jones and Jim Carrey, playing Two-Face and The Riddler respectively, didn't get on at all, and it was mainly the former's fault. The No Country For Old Men star has a reputation for being extremely miserable and tough to get along with, and he reportedly loathed working alongside the comedic Carrey, who was being lauded as one of the finest movie stars on the planet at the time. Jones didn't take him seriously as an actor, with Carrey claiming that he said to him:
"I hate you. I really don't like you ... I cannot sanction your buffoonery."The rapport between the two in the film is actually quite amusing, and one of the stronger aspects of a poor movie, showing that you don't have to get along to have good on-screen chemistry.
