Robert Downey Jr wants a Black Widow film, and then some

The fans are itching for a movie on female superhero

, played by Scarlett Johansson, but

feels the film can wait because the actor deserves a break as she is going to be a mother.

The 49-year-old actor, who has been a part of Marvel's The Avengers, and Iron Man franchise, 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. "It would be kind of more appropriate for a character that already was like a Black Widow (to lead a movie). It just seems like whatever Scarlett does people want to go see it," he added.

"Look, I think that the interesting thing particularly after Guardians... with Zoe (Saldana), (or) even Pepper from the first Iron Man. 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.
