Lots more ninjas in this one, unsurprisingly. G.I. Joe: Retaliation was supposed to come out last summer, but the decision to post-convert it to 3D and maybe put a little more Channing Tatum in it took a couple months. Now Paramount is getting ready to promote the thing again, and here’s a pretty cool new Japanese trailer that gives an bit more screen time to Storm Shadow, the evil ninja played by Lee Byung-Hun. The plot hasn’t changed: the Joes are framed as traitors and on the run from their own government as well as COBRA and they need to clear their name and blast the bad guys. Simple and fun. G.I. Joe: Retaliation opens on March 29, 2013.
