Joss Whedon says it’s “very doubtful” he will return for ‘Avengers: Infinity War’

“I couldn’t imagine doing this again,” he reveals, referring to the time and effort which has gone into the sequel. “It’s enormously hard, and it be, by then, a good five years since I created anything that was completely my own. So it’s very doubtful that I would take on the two-part Infinity War movie that would eat up the next four years of my life. I obviously still want to be a part of the Marvel Universe – I love these guys – but it ain’t easy. This year has been more like running three shows than any year of my life. It is bonkers.”
