On Tuesday, tickets for Marvel's highly anticipated Avengers: Endgame finally went on sale. The announcement came after a mini-trailer for the film was released, which revealed plenty of new footage featuring Earth's Mightiest Heroes in action.

Now, with the release of the film now only weeks away, the marketing for the film is entering its final phase. A new television spot for the film was just released and, while brief, it still offers a bit of new material.

While some of the shots in this 30-second spot have already been seen in previous trailers, there is also some new footage, like Captain Marvel looking at the pictures of the characters who died following Thanos' Infinity-powered finger snap. We also have a new glimpse of a weary Tony Stark, which could be taken when he is still stuck inside the Guardians' spaceship.

Plus, a new action scene features both War Machine and Rocket in the middle of an explosion. But what's most noteworthy is Thanos' narration in the TV spot. "The work is done. I won. What I'm about to do... I'm gonna enjoy it. Very, very much," the Mad Titan says, as Thor, Captain America and Iron Man all approach the supervillain for an epic battle.

While fans might worry that the promotional material of Avengers: Endgame will reveal too much, the film's massive runtime, which is currently reported as three hours and two minutes, indicates that what Marvel is choosing to show us is only the tip of the iceberg.

"Joe and I like very propulsive storytelling," co-director Anthony Russo recently said in an interview, when addressing the movie's runtime. "We like to keep it tight and focused, and to give the audience a thrill ride. But this movie… you know, no one’s been pushing us to cut the film. We usually are; we’re primarily pushing ourselves. The number of characters, the scope of the story, the fact that it was a conclusion. It’s just that everything lined up [so] that it was going to be a difficult story to tell. Meaning that it would require a lot of screen time to tell it properly."
