Perhaps upping the ante on the teaser of the first teaser trailer, Marvel Studios has released a video featurette marking last month's start of production of 2018's Avengers: Infinity War.
The 03:37 video covers mostly ground fans are already familiar with, but does confirm some long-assumed things about the film, including that it will feature the Guardians of the Galaxy along with the Avengers, and will also feature Tom Holland as Spider-Man.
The video also reveals at the start of the film the Avengers are "basically a name with nobody in it" due to the continued fallout of Captain America: Civil War and the fractured relationship between Tony Stark and Steve Rogers, and that Stark senses the approaching threat of Thanos and is doing "everything in his power to keep the Earth safe."
Earlier in the evening Robert Downey Jr. did a Facebook Live chat from the Pinewood Studios set in Atlanta, GA in which he confirmed several of the same things as the video feature.
