#1 The whole cast — Avengers: Infinity War – Part 2
With the second installment of Avengers: Infinity War not set to hit cinema screens until May 3rd, 2019, speculation as to the cast is as yet vague and unclear. Interestingly, which of the original comic book characters will actually make up the cast is also as yet unclear — the movie is seen as a culmination of all of the preceding Marvel movies set for release in the next few years. The cast of Avengers: Infinity War — Part 2 will entirely depend on who survives the Marvel movies of the next five years, and could see an almost entirely different cast of Avengers altogether.
In addition to this, it is uncertain as to whether the contracts of big Marvel names such as Robert Downey Jr. and Chris Hemsworth have been renegotiated, which means that we may see their characters in just one of the two parts — only time will tell.
