"It's a decidedly masculine role and we live in a time, where a lot of actors are very effeminate and there's a masculine component to the role and there are guys out there like Russell Crowe and Eric Bana who bring a good physicality and do what they do, but I don't know if they're exactly right at the end of the day. Josh Brolin is a very exciting actor, so we'll see," Moviehole quoted McG, as saying.
As for whether Robert Patrick will reprise his role from Terminator 2 for Terminator 4, McG said: "There will be a suggestion of the liquid metal development and a suggestion of the T-800 development. "It's going to be a tip of the hat. We're undecided if there's going to be an actual appearance," he added.
