When the first teaser trailer for The Expendables 3 hit the internet back in December, there wasn’t a whole lot to see other than a group shot with a giant list of names. Now this week Lionsgate has released a new “Roll Call” trailer that gives a few brief glimpses of action (including an intriguing train set piece) before once again running down the huge roster of action stars both new and old. They’re definitely marketing this as the final installment, although whether or not that ends up being true probably depends on how well it does. What do you think, does this look any better or worse than the first two movies? The Expendables 3 hits theatres on Aug. 15th; check out the trailer and an assortment of 16 character posters after the jump.
