Terminator Salvation is still month away from its release date but the overwhelming positive fan reactions have led production company Halcyon to announce plans for a fifth instalment already.

Halcyon Co. heads Derek Anderson and Victor Kubicek have confirmed they are developing a fifth installment in the Terminator franchise. According to Variety, director McG, who directed the upcoming fourth film, Terminator Salvation, is working with the Halcyon duo on the latest project.

This doesn't come as any great surprise, because Christian Bale signed for three films. Terminator Salvation is just the first movie in a planned trilogy.

Terminator Salvation is set to hit theatres on June 5.
