In a recent interview, Whedon had nothing but praise and excitement for James Gunn’s work on Guardians of the Galaxy, but it seems like all that enthusiasm won’t affect Avengers 2 as the director has claimed that there will be no overlap between the two movies.
This certainly puts a crimp on the rumors that supervillain Thanos will be introduced first on Guardians of the Galaxy, before becoming the main antagonist in Avengers 2. Whedon himself stated that the two films will be completely separate:
“We’re following Guardians at Shepperton Studios,” revealed Whedon, “but we won’t be swapping cast members. Every movie is its own thing and has to be. Unless I take a lot of peyote and write a very different draft… and I’m not ruling that out.”
