With just one month until the worldwide release of Avengers: Infinity War, Marvel Studios has marked the occasion with the release of a minute-long promo featuring glimpses of new footage, a snippet of new dialogue, and a better look at a back-talking Teen Groot.

Among the new elements are a detail look at Iron Man's transforming "bleeding edge" armor, a shot of Elizabeth Olsen's Scarlet Witch, and Chadwick Boseman's T'Challa declaring, "Today we don't fight for one life, we fight for all of them." Plus, yeah, Groot has a potty mouth, apparently.

As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment – the fate of Earth and existence itself has never been more uncertain.

Directed by Joe and Anthony Russo, Avengers: Infinity War stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Paul Bettany, Anthony Mackie, Paul Rudd, Elizabeth Olsen, Tom Holland, Benedict Cumberbatch, Chadwick Boseman, Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Vin Diesel, Tom Hiddleston and Josh Brolin, among others.
