My friend tipped me off that Christian Bale may be starring in "Terminator 4: Salvation" which is scheduled to open in 2009. Rumor is that Bale will star as John Connor who leads the resistance against the machines. (This sounds eerily like another "Reign of Fire" to me, folks!)
The last Terminator movie, "Rise of the Machines," left off with Nick Stahl starring as John Connor. John and his future wife were last seen hiding in a VIP underground bunker. John started giving the US military orders via a ham radio as the world went to hell around them. Neither director James Cameron or Governor Arnold Schwarzenegger are involved with Terminator 4 at this time.
