Josh Brolin’s portrayal of Thanos in Avengers: Infinity War is one of the highlights of the movie from an acting standpoint as well as from a visual effects perspective.
Infinity War gave Marvel Cinematic Universe fans their first real look at Thanos, giving much of the film to him.
In addition to Josh Brolin’s exaggerated body movements, the voice of the character is also somewhat different than what ended up in the final cut of Infinity War.
The footage shows the Mad Titan having a conversation with Loki, who is not seen.
