Who wouldn't want to see "Avengers 2" star Scarlett Johansson in her very own "Black Widow" movie franchise; Even her co-star Robert Downey Jr., who has been the long time poster boy for Marvel, wants it when asked by USA Today.

"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."

However, he did mention that before doing a movie his Avengers co-star should take some time off with her family.

"Doesn't Scarlett deserve a break?" he quipped noting that Johansson has just given birth. "Look," he added, "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."

"Avengers 2" star Robert Downey Jr. even noted that Scarlett Johansson's "Black Widow" character is not the only one who deserves a stand-alone film, even Jeremy Renner's "Hawkeye" deserves one.

"The funny thing is honestly at this point everyone deserves a franchise. I think Jeremy Renner is - when folks see the Avengers: Age of Ultron he's just a rockstar, a bada-. And Ruffalo is pumped. He does great (work). I'd like to hear them talk even more seriously about a Hulk franchise, because that's been one of the toughest ones to get right. But I'm sure that my parent company is feeling expansive and and bold after the summer they've had."

"Zero Dark Thirty" actress Jessica Chastain even called out Marvel and asked them to make a stand-alone film for the red-haired female superhero during her interview with The Wrap.

"Where is the Scarlett Johansson superhero movie? I don't understand it, why is it taking so long for this?" Chastain asked TheWrap. "This woman clearly shows that people want to go see her in the movies. 'Lucy,' didn't it beat 'Hercules' by a lot opening weekend, when it was made for a lot less? She shows that she kicks ass, she's a great actress. 'Under the Skin' is an incredible film, and why are we still waiting for a go-ahead on a superhero movie starring Scarlett Johansson?

"To me, it's a no-brainer," the actress added. "You want to make money, put Scarlett Johansson in a superhero movie!"
