Seriously, Christian Bale is the best choice to play John Connor. He is one of the most charismatic actors to grace silver screens.

I wont even think of watching T4 is Nick Stahl was coming back as John Connor.

But, Arnold was the guy who made the Terminator franchise popular in the first lpace.

Oh yeah, Edward Furlong is a fat guy now, and I dare not imagine how he would take on the machines in his current state. He is also the worst choice for John Connor. He is a drug addict by the way.
