Available now for free on the Nintendo 3DS eShop is the Green Lantern movie trailer. This is the first movie trailer that has been released through the eShop, and should be an indication of the movie viewing capabilities the system has to offer. The trailer runs for over 2 and a half minutes and can be viewed in full 3D.
This should also act as a nice little tease before Netflix releases for the system, which is still slated to release sometime during the summer. Movies + Nintendo 3DS = not too shabby.
