It seems that Tobey McGuire and Sam Raimi haven't officially committed to returning. I thought they had. Kirsten Dunst hasn't been confirmed even though she's stated that she'd like to return.
Simmons has been great as JJJ. Could we see more of him in the next movie?
“I saw Sam [Raimi] at his Christmas party. We’ve definitely brainstormed ideas for Triple-J, but I have no desire to make Triple-J more of the focus of those movies,” he said. “The amount that I did in 1, 2 and 3, is just exactly right. Like be the wolf. Come in, blow in, do a week, blow out, be the comic relief, and hit the road. And let Tobey and everybody else do the heavy lifting.”
That is true. He came in, nailed his scene and was done. At least the writers will have a year to knock out a really great script. I hope they will watch the previous films and not make the same mistakes. I've enjoyed the movies but to be honest, there is room for improvement. I look forward to hearing more about this.
