Edgar Wright's approach was actually not involving the character with the bad marriage, Paul Rudd was set to star as the second character to don the Ant-man mantle whose a single-father.

I am truly curious to see what caused this divide considering the film only exists because of Wright's script and vision. So far all we're getting is the normal PR "amicable split".

Twitter "insider" gossip suggests that Wright was falling way behind schedule and Disney was nervous that he wouldn't be able to handle a project this big, so they let him go. If so, it's very kind of them to suggest that he left because of "creative differences." Lets Disney do what's best for them while still letting Wright look like the good guy.

This is still a shocker. I'm not a Paul Rudd fan but I like Edgar Wright. I wish the article gave some details.

As it is, all we know is Disney made the decision on Wednesday and waited to tell him Friday afternoon, so that Wright wouldn't make a scene in the office. 

I dislike him. Not really a huge fan of most comic actors these days or modern comedy films.

Yeah, not much to add, really.
