Just when it looked like Big Arnie was on his way back – what with “Terminator 3” ruling the box office and all, and plans underway to do sequels to some of his biggest hits – comes news that the Austrian Oak has agreed to another comedy. Oh heck. According to The Hollywood Reporter, Schwarzenegger’s said yes to “Big Sir”, which revolves around a man who must travel cross-country with his future stepkids as they’re pursued by unsavory characters. The film marks the second potential project lined-up for the actor, the other being Warner Bros. Pictures sci-fi remake Westworld. But Arnold…a comedy? What are you thinking?
