To bring prospective filmgoers to movies over the past several decades, film companies have relied on flat film trailers. That time is over. Enter now the realm of virtual reality, complete with Iron Man and the rest of the Avengers crew. Today the folks at Marvel have released a virtual reality trailer for the Avengers: Age of Ultron film that also debuts this weekend. This trailer works on all Android devices, iPhones, and the Samsung Gear VR - as well as Oculus Rift, of course.
