Arnold Schwarzenegger and Bruce Willis have signed up for “substantial” roles in The Expendables 2, rejoining Sylvester Stallone in the sequel to the most bloodthirsty Cialis commercial ever conceived. Both actors had cameos in the first film that amounted to little more than a wink among a feature-length nudge, but with the first Expendables clocking in at over $200 million—and, respectively, a career-derailing sex scandal to overcome and an aging franchise to reboot—Schwarzenegger and Willis obviously had a lot of interest in the story and characters this time, which must be very compelling indeed. "There is some real substance here," they probably said. But while the specific plot details on the Simon West-directed film remain hazy, most rumors have involved who will fill out the rest of the ensemble, a roster that still evokes a fevered hallucination in the aisles of a mid-’90s Blockbuster Video.
