Even as someone who hated T3...no not hated, more like abhored, detested, loathed, etc.... Ill still be looking forward to this, especially if they go ahead without Arnold, Ill probably be let down again as its by the same guys but whateverTerminator 4 is ready to start production in 2005, but will Arnold Schwarzenegger be back? Variety reports that Terminator 3: Rise of the Machines writers John Brancato and Michael Ferris have completed a draft of a script that was developed under the supervision of "T3" director Jonathan Mostow.
Schwarzenegger's availability is the big question mark, since he is the governor of California. There's already been talks for Arnold to return, but it would likely be in a limited role. Variety adds that the expectation is that "T4" will break in a new terminator model.
