The "Avengers: Infinity War" movie might be years away, but fans are already anticipating a blockbuster entertainer. The script leaked indicates a firm possibility of cameo roles by both Benedict Cumberbatch and Chris Pratt.

Marvel Studios is being expectedly secretive of the details on this movie. However, Cumberbatch has indirectly hinted at his role in the movie as Doctor Strange when he mentioned having to schedule meets with the four actors who play "Thor," "Scarlet Witch," "Vision," and "Iron Man" in-between his already full schedule, University Herald reports. The actor further added that "Doctor Strange" was pretty important to opening the next chapter in the storyline. In fact, Cumberbatch is apparently all set to have a cameo role in "Thor: Ragnarok" as well.

As for Chris Pratt, aka "Star-Lord" in the Marvel Cinematic Universe - has a two-fold purpose as the Star-Lord, or Peter Quill and also as the bridge who will bring the "Guardians of the Galaxy" team to the world of "The Avengers," ComicBook.com reports.

Reportedly, Pratt will have a pretty sizable role in the storyline as the Star-Lord, but fans are also looking forward to seeing the witty Peter Quill interacting with "The Avengers" team. As for the rest of Star-Lord's teammates, though, there has been nothing to indicate which of the other Guardians we might see in Infinity War - or if we will see cameo roles of any of the others at all.

Vin Diesel had already confirmed earlier this year that the 'Guardians of the Galaxy' would definitely feature in "Avengers: Infinity War." So, the Star-Lord's probable role in the movie is a much less surprising rumor than Cumberbatch's possible role in the movie.

However, with Marvel Studios not confirming either character's role as of yet, these rumors remain just possibilities of what fans can look forward to with "Avengers: Infinity War" Part 1 and Part 2 releases, slated for a 2018 and 2019 release.
