The "G.I. Joe" film is nothing if not bombastic, so it's no surprise that there were dozens of special effects wizards working on the many CGI-heavy scenes. One of the flick's most explosive moments concerned an attack on a US Army helicopter resulting in its destruction.
In this exclusive clip from the DVD's bonus features, the crew shows exactly what went into creating that memorable sequence, from multiple angles and computer-generated layers. The film hit Blu-ray and DVD today.
