Which aging action icons are left to appear in the franchise?
"I have come here to chew bubblegum and kick ass...and I'm all out of bubblegum." With that iconic line - voiced in John Carpenter's 1988 cult classic "They Live" - wrestler-turned-actor Roddy Piper entered the pop-cultural lexicon for all time. While his film career never quite gained a full head of steam, the WWE star nevertheless racked up a long list of film credits in such micro-budget fare as "Hell Comes to Frogtown" and "Immortal Combat." Not to mention, his recent self-referential turns (he appeared on an episode of FX's "It's Always Sunny in Philadelphia" as a professional wrestler named "Da' Maniac," among other things) also show he has the sense of humor required to take on a role in the "Expendables" franchise. Have him evoke that famous "bubblegum" line and the crowd will eat it up, guaranteed.
