Scarlett Johansson on why she didn't mind being second choice for Marvel's Black Widow

After eight Marvel films over the last 10 years featuring Scarlett Johansson as Black Widow, it's hard to imagine anybody else portraying the super hero.

But in an interview with Parade magazine published Friday, the Oscar-nominated actress opened up about not being the first choice to play her iconic character — and how it made her appreciate the role even more.

Though Johansson said she had a "wonderful" meeting with "Iron Man 2" director Jon Favreau, she was ultimately passed over for Black Widow, real name Natasha Romanoff, in favor of Emily Blunt. But when Blunt couldn't accept the part because of scheduling concerns, it was Johansson's.

"I was really excited to work with him," Johansson said of her meeting with Favreau. "So I said, ‘If this doesn’t work out, I’m an actor for hire, so call me anytime.’ ”

Natasha Romanoff (Scarlett Johansson) gets her solo Marvel movie with "Black Widow."

According to Johansson, she has no ill feelings about being second pick.

“The best call you can receive is after you are rejected for something and then you get it,” she said. “You appreciate it more. I’ve basically made a career out of being second choice.”

The actress also described the moment she realized how special the Marvel films were. According to Johansson, the realization came while filming a scene in 2012's "The Avengers." 

During the shot, Black Widow, Iron Man, Thor, Captain America, Hawkeye and the Hulk stand in a circle while gearing up for battle.

These are all the movies delayed by the pandemic

“It’s the iconic hero shot,” she said. “We were all thinking, 'This is crazy!,' because these worlds were coming together. We’re still processing how much of an impact these movies have had."

Johansson's ninth and final Marvel film will be "Black Widow," which was originally set for a May 1 release, then backburnered due to the coronavirus pandemic. Now it's rescheduled for Nov. 6, causing a domino effect for the rest of the Marvel Cinematic Universe.
