There’s something comfortingly familiar about seeing Matt Damon beat up an international assortment of bad guys. It worked for three mostly excellent Bourne movies, and from the looks of the first trailer for this summer’s fourth installment, Jason Bourne, it’s still a potent formula as ever. Not much is revealed — chases, fights, and angry demands for the truth, natch — but with director Paul Greengrass returning to the franchise, the trailer has the same gritty look and realistic action that made the original trilogy so effective. On a side note, after watching Ben Affleck grimace and growl and murder his way through Batman v Superman with such ease, who wouldn’t pay to see him beat up his buddy Damon in IMAX 3D? Bruce Wayne v Jason Bourne, anyone?
