WARNING: Some of your favourite movie duos may be forever ruined by these revelations of celebrities who literally hate each other.
Rachel McAdams and Ryan Gosling - The Notebook (2004)
In the movie: Rachel McAdams and Ryan Gosling played one of the best on-screen couples of all time. The Notebook told the story of Allie and Noah, a pair torn apart by a disapproving family but who ultimately prove love conquers all when they find their way back together years later.
What's the beef? Gosling has said that they “inspired the worst in each other” during the making of the film. This week on the tenth anniversary of The Notebook, director Nick Cassavetes commented on a particularly heated incident between the two
"He's doing a scene with Rachel and he says, 'Would you take her out of here and bring in another actress to read off camera with me?'
However it seems like the relationship was able to be mended albeit temporarily- the pair dated from 2005 until 2007.
Brad Pitt and Harrison Ford - The Devil's Own (1997)
On screen: New York police sergeant Tom O'Meara (Harrison Ford) unknowingly takes in terrorist Frankie McGuire (Brad Pitt), an IRA gunman on the run from the British military. The two initially bond but their innate differences soon lead them to conflict.
What's the beef? Brad Pitt was excited to be working with then much more established actor Harrison Ford, however when the script moved its focus from Pitt's character to Ford's the feud began.
The film was delayed as the stars fought over the script and the budget was blown. Brad Pitt even announced before the film release that he had tried to abandon the project. Somewhat unsurprisingly The Devil's Own was a box office failure
Robert Downey Jr and Terrence Howard - Iron Man (2008)
On screen: Robert Downey Jr plays Iron Man aka Tony Stark and Terrence Howard plays his best friend Lieutenant Colonel James Rhodes. Rhodes helps his friend as Stark creates and becomes the superhero Iron Man.
What's the beef? Iron Man was a huge success and it seems like the relationship between Downey Jr and Howard was fantastic but all that changed when Howard was dropped from the cast of Iron Man 2. In November 2013 Howard was quoted as saying
it turns out that the person that I helped become Iron Man, when it was time to re-up for the second one, took the money that was supposed to go to me and pushed me out
When Howard was asked how things with Downey Jr were now he replied
Oh, I love him. God's going to bless him
Hmmm...I somehow think that sounded a bit more sarcastic in the interview.
Jamie Foxx and Colin Farrell - Miami Vice (2006)
On screen: Friends Sonny Crockett (Colin Farrell) and Ricardo Tubbs (Jamie Foxx) work together as undercover cops trying to bust a drug trafficking cartel. However in the dangerous and high stakes environment Crockett becomes romantically involved with a wife of one of the drug traffickers leaving Tubbs fearing for their safety.
What's the beef? When the two first signed on for the film Farrell was the bigger star but after Foxx won an Oscar for the film Ray it was reported the actor developed such an ego it made him very difficult to work with.
Initially Jamie Foxx was paid less than Farrell but due to Foxx causing such problems his paycheck was increased while Farrell's took a cut. During filming the two avoided having scenes together and after Foxx refused any more international travel for the film, the entire end of the script needed to be rewritten to be shot domestically.
C3PO and R2D2 - Star Wars (1977)
On screen: C3PO and R2D2 the lovable droid duo are rarely seen apart throughout the whole Star Wars series. Although the robot pair had their squabbles they were always there for one another.
What's the beef? R2D2 actor Kenny Baker has gone on record many times talking about his dislike for Anthony Daniels who plays C3PO. When asked if he was friends with Daniels, Baker replied
Not really. I thought it was just me he didn’t get on with but recently I’ve found out he doesn’t get on with anyone....we could make a fortune touring around making personal appearances. I’ve asked him four times now but, the last time, he looked down his nose at me like I was a piece of shit. He said: ‘I don’t do many of these conventions — go away little man.’
Despite these comments it looks like they're putting those differences aside as both have signed on to appear in Star Wars: Episode VII.
