When the right to Teminator were sold, it appears that Nick Stahl was part of the deal. We get the skinny from our friends at joblo:
Will actor Nick Stahl return to the role that Edward Furlong once made excruciating? TERMINATOR 4 will apparently involve John Connor’s futuristic crusade against those metal motherf*ckers, and ‘Master Sgt. Candy’ tells us that (as rumored/expected) Stahl is not only part of the “option package” on the sequel(s), but is indeed giving consideration to coming back (we suspect he’s being assaulted with bags of legal tender).
I really have a strong dislike for Terminator 3. I cannot even give an honest opinion of Stahl’s performance in the film because I was just so angry as I watched it, that I wrote off everything about it. The fact that he was even in T3 makes me mad at him, this is unreasonable and yet I live with it.
If they do T4 set in the future I think it may be best to get another actor to play John Connor unless Stahl decides to go to rugged man camp and get surly. The future robot wars is where T3 should of happened. It is a movie that needs to be made and it is a perspective that if done well, will add a lot of depth to the series. Plus it is no secret that we love robot on robot, robot on human violence around these parts.
T1 and T2 were awesome T3 sucked, If they must make more – I hope the return to awesome is swift.
