Tyrion Lannister may share screen with Tony Stark and Steve Rogers. "Game of Thrones" star Peter Dinklage is in talks to join the cast of both "Avengers: Infinity War" and its currently untitled sequel.

There hasn't been any comment from Marvel about Dinklage's involvement, but a source has told Variety that Dinklage will play key role, although the details are still under wraps.

Dinklage won a Golden Globe and two Emmys for his portrayal of Tyrion Lannister. In 2014, he played villain Bolivar Trask in "X-Men: Days of Future Past", so he is no stranger to portraying comic book character. If Dinklage does join "Infinity War", it will be his first involvement with Marvel Cinematic Universe.

Although full cast hasn't officially been announced yet, "Infinity War" will presumably feature the largest cast among other Marvel movies to date. Chris Evans and Robert Downey Jr. are expected to return as Captain America and Iron Man/Tony Stark respectively. The plot may focus on the alliance between the Avengers and the Guardians of the Galaxy to fight villain Thanos, who may collect Infinity Stones to achieve godlike powers.

"Infinity War" and its sequel are planned to be filmed back-to-back, with Atlanta and Scotland as their settings. Joe and Anthony Russo, who directed "Captain America: The Winter Soldier" and "Captain America: Civil War", will serve as the directors.

"Avengers: Infinity War" is scheduled to arrive in U.S. theaters on May 4, 2018.
