Actors live and breathe their characters (quite literally), so it's not surprising they sometimes have a lot of thoughts on how their stories should (or shouldn't) unfold. Here are some movies which were changed in pretty major ways as a result of actors absolutely refusing to do certain storylines...

The original The Addams Family script concluded with the reveal that Christopher Lloyd's character was not, in fact, Uncle Fester, but a con artist. Basically everyone in the cast was upset about the plot point, it seems, with the exception of Christopher Lloyd himself. But it was a young Christina Ricci who actually convinced the director, Barry Sonnenfeld, to change the story.

"Everyone was upset except Christopher Lloyd. But the person who best articulated their concern was Christina," Barry told Entertainment Weekly. He altered the plot so that the character turned out to actually be the real Fester, suffering from amnesia.

Pitch Perfect 3 features the character of Theo, a music executive who works with Anna Kendrick's character Beca. Originally, he was also meant to be her romantic interest, but Anna Kendrick protested. "Originally the music executive was supposed by my romantic interest but I said no to that, because I thought that would be kind of fucking problematic," Anna told Harpers Bazaar.

"I was like, 'Can no one else [see it]?' Once I said it, everybody was like, 'I guess so'... And they still wanted to have a version at the end when we kissed, and I still said no."

The original The Fast and the Furious script apparently featured a love triangle between Brian, Dom and Letty, but Michelle Rodriguez, who plays Letty, threatened to quit if they didn't change it. "It was more of a Point Break idea," Michelle told The Daily Beast.

"They just followed the format without thinking about the reality of it. Is it realistic for a Latin girl who’s with the alpha-est of the alpha males to cheat on him with the cute boy? I had to put my foot down. I basically cried and said, 'I’m going to quit,' and, 'Don’t sue me, please — I’m sorry, but I can’t do this in front of millions of people.'" In the final movie, Letty stays loyal to Dom.

Meryl Streep was virtually unknown in the film industry when she was being considered for the role of Joanna, a woman who leaves her husband and child, in Kramer vs Kramer. Still, she fought for the character to be changed before she'd agree to take the part, describing Joanna in the (deliberately anti-feminist) book that the movie was based on as "an ogre, a princess, an ass."

Meryl fought for the character to be much more layered, and for the reasons she leaves her husband and child to be much clearer and more nuanced. She also argued that the ending, in which Joanna wins full custody of her child but relinquishes it, should be motivated by Joanna's love for her son and not her own selfishness, as it seemingly was originally. Meryl even wrote Joanna's iconic courtroom speech herself.

In an early version of the script for Star Trek V: The Final Frontier, Spock and McCoy join forces with Spock's villainous half-brother Sybok against Captain Kirk.

Actors Leonard Nimoy and DeForest Kelly insisted their characters would never willingly betray Kirk, and the plot was tweaked so Spock and McCoy ultimately back Kirk up.

Emma Watson refused to be in a scene in This is the End that involved Channing Tatum in a gimp costume when the improvisation involved went in a direction she wasn't prepared for.

Seth Rogen, who not only starred in This is the End alongside Emma but was also co-writer, co-director, and producer for the movie, took responsibility for Emma's discomfort, saying, "I, for sure, should have communicated better and because I didn't, she was put in an uncomfortable situation. She and I spoke on the night; it was overall a shitty situation and it must have been hard for her to say something. And I'm happy and impressed that she did. We agreed on her not being in the scene together."

Point Grey

Both Robin Williams and Sally Field reportedly pushed back against studio execs who wanted their characters, Daniel and Miranda, to get back together at the end of Mrs Doubtfire.

Robin apparently said the idea was a "fantasy" that could be harmful to kids whose parents are divorced. Instead, the movie has a more realistic version of a happy ending: Daniel and Miranda have a civil relationship and share joint custody of their kids.
