While fans eagerly await the premiere of behind-the-scenes footage, to say nothing of a second full-length trailer, Marvel Studios has debuted a new 30-second television spot for Avengers: Infinity War, ominously titled "The End."

There's no additional footage in this promo, but there is a new line of dialogue: "The end is near," uttered by a mysterious male voice.

While Thanos might seem like the obvious character to speak such a phrase, that definitely isn't Josh Brolin's voice. So, is it possible we've heard one of the members of the Mad Titan's Black Order speak for the first time? Perhaps we'll find out for sure when the next trailer arrives, which Marvel Cinematic Universe devotees certainly hope will be soon.

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, 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. The film arrives April 27.
