Actor Mark Ruffalo
, who plays Bruce Banner/the Hulk in The Avengers franchise, said that he wants actor Zoe Saldana to play his on-screen cousin Jennifer Walters.
The 46-year-old actor said Saldana would be his first choice as he thinks the actor would be great as She-Hulk.
"Well I think Zoe Saldana would be a great She-Hulk. It'd be nice to see someone like her join The Avengers
. Or someone quiet and demure like Emma Stone would be nice. But it would be up to the powers that be," he said.
Both actors have prior experience in Marvel Comics movie adaptations.
Saldana will play Gamora - another green-skinned superhero - in Marvel Studios' Guardians of the Galaxy, which will be released next month.
Stone starred as Gwen Stacy in Marc Webb's two Amazing Spider-Man' films at 20th Century Fox.
Ruffalo recently revealed that Marvel is considering a new Hulk solo movie.
Joss Whedon's sequel Avengers: Age of Ultron will be released in the UK on April 24, 2015 and in the US on May 1.
