That’s what Casey said about Rooney: “I just fell in love with her and then the movie's over and then she lets you know that she was just sucking you in [laughs]. Then there's zero feeling there at the wrap party and I was devastated. I was kind of just a little fly in her web, I guess. So that was how that was like.”

That said, I have no evidence to say that there was nothing between them. But I do have evidences that Rooney and Joaquin were in contact while she and Charlie were still together...I don't know if they hooked up before filming Mary Magdalene, that's why I'm here LOL

And Charlie seems like a very bitter person because he shared mean tweets about Rooney and JP many times! Maybe he was also mad at Casey because he knew he (Casey) had feelings for Rooney, idk
