The 49-year-old actor, who has been a part of Marvel's 'The Avengers', and 'Iron Man 3', said though Johansson would attract audience if she reprises the role of Black Widow, there are many other female characters in Marvel films that deserve the limelight, reported Aceshowbiz.
"Doesn't Scarlett deserve a break?" he said with a laugh, noting that Johansson is pregnant with her first child.
"Look, I think that the interesting thing particularly after 'Guardians...' with Zoe (Saldana), (or) even from the first 'Iron Man' where Pepper was kind of this really, to me the 'Iron Man' franchise would never have taken off without (Gwyneth) Paltrow.
"There's something about her that grounded the story. She's not your typical lady in a superhero movie, and then by 'Iron Man 3' she's swallowing serums and putting on suits and kicking (butt) and all that stuff," he said.
