Well, that's one way to do your Matt Damon interview.
After a segment on celebrities turning heroic by helping out regular folks in trouble, Stephen Colbert ran backstage and immediately pulled a soda machine over on himself. He then waited for someone famous to come by and rescue him. As luck would have it, his interview guest Matt Damon was there.
Unfortunately, instead of saving the "Report" host, Damon just chatted about his new movie "Elysium."
