Everyone knows Emma Watson as Hermione in the Harry Potter films and...well, that's probably all you know her from. She's currently filming the movie Noah. Emma was also going to appear in the 2013 movie that Seth Rogan is directing, The End of the World, and on-set pictures were taken of Emma with Rihanna, who is also in the movie.

But will Emma actually be in The End of the World? That remains to be seen. During filming, an extra by the Tumblr username of "sleazzyweasley" posted that Emma had become offended at improv during a scene and had walked off the set:

So Emma had already filmed a scene last week at “James Franco’s party” and was coming back Wednesday and Thursday to film another scene with Channing Tatum, Danny McBride, Seth Rogan, Franco and Jay Baruchel.

The scene was as raunchy as it could be. Seth, Franco and Kay are kneeling on the ground with a few “cannibals” over them (that’s me) waiting to eat them as McBride comes out of an RV as our “king” with Channing Tatum on a leash in only a thong.

Emma knew he was going to be in a thong and everyone knows he used to be a stripper. So things were starting to get raunchy. Emma steps on set and looks at the scene and all of us in it and kind of has a freak out moment. Before we started to film she stormed off set with her publicist and Seth was saying what happened what’s wrong with Emma? Then she came back and filmed about 3 minutes of the scene.

During the scene Channing decided to do some of his breakdancing in front of her but alas he was in nothing but a thong.

So Emma storms off set. Everyone’s like WTF where is she going? She walks all the way down the street. So we wrapped the night 5 minutes later.

Came back last night and found out she quit because she the scene was too raunchy and she was really pissed that Channing was drinking while filming. He was obviously smoking weed as well.

But who can blame her right? She has a good image to uphold. But her quitting made last night filled with Emma jokes.

The ground was wet and muddy and Channing said we were stepping in Emma’s tears.

Anyway, there’s the story. I’m headed back on set till 6am. If y’all have more questions send them, I will be bored.

"sleazzyweasley" deleted this story off of her of Tumblr, but not before another Tumblr user known as "itsemmawatsonbitch" reposted it.

I didn't believe this story the first time I heard it. Despite what I think about Emma Watson, which is that she got lucky and will be out of Hollywood once it's realised that her looks are a dime a dozen and that she can't act, I didn't think that she would do this. I thought that all or part of the story must be fake.

As it turns out, the only mistake in the story was that "sleazzyweasley" got the name of one of the actors wrong. It wasn't Channing Tantum; he's not even in The End of The World. The actor of whom "sleazzyweasley" was speaking was actually James Franco and he corroborated this story in an interview he did with Mila Kunis for Interview Magazine:

JAMES FRANCO: So a funny thing happened on this movie I'm doing down here in New Orleans that made me think of you. The movie is a comedy, but it's kind of an outrageous one, and this actress—I won't say who, but she had a smaller role in the film—walked off the movie in the middle of a scene.

MILA KUNIS: This is Seth [Rogen]'s movie that you're talking about?

FRANCO: Yeah. I'll admit that the scene we were doing was pretty crazy. There's not any nudity, but it is pretty outrageous. It's not as if the scene wasn't in the script, though. In any case, I didn't see any of this go down, but I guess she basically went up to the directors, Seth and Evan [Goldberg], and said, "I don't think I can do this." She, by the way, didn't have to do anything crazy in the scene. But what was going on around her was, I guess, too extreme for her. So Seth was like, "Well, what can we do to fix it?" And she said, "There's nothing you can do to fix it. It's just everything." And he said, "Well, let's just shoot it and I promise you can come to the editing room, and, if you don't like what we've cut together, then we will not put it in the movie." And she said, "No, that's still not good. I just can't do this. I can't be here." And he said, "Do you want to leave?" And she said, "Yeah, I've got to leave."

KUNIS: What?

FRANCO: Yeah, so she left. But what I'm really leading to is that my experience working with you has, in many ways, been the opposite of that.

KUNIS: I guess you could say that I have no shame. [laughs] I mean, if you think about all the stuff that you've made me do—just you alone, James . . .

FRANCO: We can get into that if you want.

KUNIS: We don't have to get into details, but that poor girl would never be able to do a short with you. She would never be able to have fake blood thrown at her, with blood-sucking vampires and dildos being thrown everywhere.

FRANCO: At this point, we might need to explain that you and I worked together many times before. I'm sure that some people know that we did a Funny or Die video together, and then we did Date Night, and then we just acted together inOz: The Great and Powerful, which was directed by Sam Raimi. But we've also done a bunch of side projects together. There is one that we did in a trailer with my hair-and-makeup person, Nana Fischer, that I don't know if anybody will ever see. [both laugh] We did a feature called Tar—that one people will definitely see. And then there's the one you're referring to where you play a leather-clad, bow-and-arrow-wielding vampire killer, and let's just say that there is lots of blood and gore.

KUNIS: Yes. That would not be okay for that girl. I, on the other hand, am game.

I won't tell anyone what to think about Emma's behaviour on the set, but I find it unprofessional and believe that this incident explains stories of Emma's diva behaviour on the Harry Potter set.

What it also odd is that Emma's publicity team isn't covering it up. Her official website and official Facebook page still say that she's filming the movie.

Given that James Franco's interview came out this month, my guess is that Emma has not rejoined the cast. So why no damage control? Is it because Emma's PR team doesn't think that the story will get out? Well, I guess that's where I come in, but I can't take all the credit.
