After calling Guardians of the Galaxy 'the best Marvel movie ever', Iron Man star Robert Downey Jr. has said that all The Avengers characters deserve a standalone film and this includes Black Widow and Hulk.

USA Today, during a recent interview, asked Downey Jr. when fans can expect to see a solo Black Widow film and the actor quipped, "Doesn't Scarlett deserve a break?"

He then continued, "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."

"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.

RDJ then also spoke about how all the other Marvel heroes (most of them from The Avengers) deserve solo films.

"The funny thing is honestly at this point everyone deserves a franchise," the Judge actor said. "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," he added.
