Actor-turned-politician Arnold Schwarzenegger is set to make his Hollywood comeback in a new Terminator trilogy. Producer Moritz Borman will start shooting the movies next year (08) and is desperate for Schwarzenegger to reprise his role as the cyborg assassin. Borman says, "We've left it open for him to maybe do a cameo." Schwarzenegger's last movie role was Terminator 3 in 2003 before he was elected governor of California.
