Mark Ruffalo’s Hulk was last seen flying out across the Caspian Sea on a Quinjet.
But from the Thor Ragnarok trailers, it’s become very clear that the Hulk has somehow found his way to the dodgy end of the Universe – where he’s become something of a gladiatorial star.
Now Ruffalo, who plays the green Avenger, has revealed that the Hulk’s bed – as seen in the trailers – reveals his backstory.
Speaking with Cinema Blend, he said: “We had to basically figure out what happened, how he got there.”
Ruffalo continued: “He was captured like Thor was – that’s how he knows Valkyrie [Tessa Thompson], and she becomes his coach along the way.
“He becomes the champion, they love him. He ends up beating the beast that the bed was made out of.
“That’s the previous champion! He tore him in half, and made him his headboard. You do all that.”
Last week Marvel president Kevin Feige revealed how the Hulk’s ending in Avengers: Age of Ultron was changed following leaks.
It now turns out the original end of Age of Ultron could have had Hulk shooting up into space, which would have been a spoiler for the Planet Hulk storyline in Thor Ragnarok.
Thor Ragnarok is released in UK cinemas on October 24, 2017.
