A brand new Avengers: Infinity War TV spot has been released ahead of the film's second full trailer. Directed by Joe and Anthony Russo, the movie unites the heroes of the MCU as they gear up for their biggest and baddest adversary yet, Thanos. The beginning of the end of everything that has transpired in the MCU over the last 10 years, the next two Avengers sequels will tie-off every plot thread in the MCU and set the stage for Phase 4 of the franchise.

With less than two months left until it hits theaters, Disney's marketing machine is ramping up for Infinity War. Just last week, a slew of EW covers - accompanied by an extensive feature on the film - rolled out and later today, a new Infinity War preview is scheduled to air on Entertainment Tonight. On top of all that, more tie-in merchandise, posters and licensed artworks for the film have been released, along with a TV spot that is devoid of new footage, but comes with an ominous warning.

Clocking in at just 30 seconds, the TV spot (see the video embedded above) starts out the same way as Infinity War's teaser trailer - with a call back to Nick Fury's iconic dialogue from 2012's The Avengers. Though the spot doesn't include any new footage, it does feature new dialogue in the form of "The end is near". That's clearly a warning of the catastrophe to come, brought about by the arrival of Thanos.

It's not clearly exactly who says "The end is near" in this new TV spot. Judging by the creepy low tone of the voice, it's presumably villain - perhaps a member of Thanos' Black Order like Corvus Glaive and Ebony Maw. Not much is known about those characters right now, though Tom Vaughan-Lawlor is confirmed to be playing Maw, and Terry Notary is reportedly playing one of Thanos' other "children". Game of Thrones' Peter Dinklage is also reportedly playing a role in the film - and while it's difficult to gauge without the full context, the slightly modulated voice could be his.

With the second and final trailer still coming, there's a good chance that we'll learn who the aforementioned enigmatic being is before the film hits theaters next month. Not that the marketing really needs to reveal anything else to get people interested in seeing Avengers: Infinity War. With so many mysteries surrounding the movie still, Marvel Studios will hopefully save more than a couple of them for the film itself to reveal.
