This is interesting, turns out someone wants make and extended version of T3 with about 40-50 minutes of additional scenes. This has never been done before, but hell I signed the petition because I want to see future sequences and more action, not to mention more story development. They would re-release it in theaters. I don't see how the director, Mostow, would allow them to do this but if the original movie is left intact, and just added to...he might not mind. Considering he origianally said if he had more money he would have made a better movie, one that would please all of the fans.
