Scarlett Johannson has replaced Emily Blunt in the upcoming Iron Man 2, according to Deadline Hollywood.

Johannson will be playing Russian spy and possible Tony Stark love interest Black Widow. Which means the nearly 44-year-old Robert Downey Jr. will be sucking face with an actress 20 years his junior.

To be fair, Blunt’s only about a year and a half older. But somehow she comes across as more woman than jailbait, no?

(Oh yeah: Mickey Rourke‘s definitely in, too.)
