With a new trailer set to bow today for Joss Whedon’s superteam flick, here’s a look behind-the-scenes (courtesy of Entertainment Tonight).

As reported yesterday, the film, which stars Chris Evans, Chris Hemsworth, Scarlet Johansson, Samuel L. Jackson, Mark Ruffalo, Jeremy Renner and Robert Downey Jr., will be known as “Avengers Assemble” in the U.K. And there’s even a shiny new poster to prove it.

The movie opens stateside in May.
