Josh Brolin is about to play a big part in the Marvel Cinematic Universe. The busy actor has landed to role of Thanos, the supremely-powerful villian who shakes up the MCU in Avengers: Infinity War. The ramifications of Infinity War are supposed to completely change the direction of the franchise. Brolin has stated the follow-up to Infinity War is still going by the generic title Avengers IV. The reason for this is the script has not been completed yet, or so Brolin believes. Even he does not know for sure what is going on with the fourth Avengers films.
That should tell fans a lot about the secretive nature of the film. Brolin’s character may be the most important villain in all of the MCU. Thanos’ arrival in Infinity War does not come without earth-shattering changes. Major characters are reportedly meeting their demise in Infinity War. The reason for this, in addition to adding a little drama to the film, is to promote many of the secondary characters to the lead.
Thanos probably will return for Infinity War. Brolin likely is signed on for several films in the MCU. Generally, Marvel Studios does not sign actors to one-film deals. The contracts are usually multi-picture deals designed to bring back the same actor in the same role for continuity purposes. Three different Batman in three consecutive Batman films did not exactly help the first Dark Knight movie franchise very much in the 1990’s.
Several other Marvel films debut in theaters after Infinity War and before Avengers IV. Maybe Brolin will play a huge part in those films as well.
