There certainly won't be more shooting. I remember reading somewhere that re-shoots are some of the most expensive outlays in movie production - and thus only done when the movie wouldn't make it to the screen without them. It was in an article regarding the J. Roberts and C. Zeta-Jones movie.
But maybe some re-editing might be in the off. Several reviewers said there were no transitions between scenes, no cohesiveness to the whole movie - maybe a truly talented editor can help that.
I find it hard to believe that a 2 hour movie has no transitions. What the hell is going on for 2 hours?
