"Avengers: Age of Ultron" continued their globetrotting to promote the movie. After hitting Hollywood and South Korea, they invaded London on Tuesday, April 21. Scarlett Johansson, Robert Downey Jr., Mark Ruffalo, Chris Evans, Chris Hemsworth, and Jeremy Renner hit red carpet for the special screening.

The Black Widow depicter looked chic in a colorful Balmain jumpsuit that she paired with YSL shoes and Bvlgari earrings. Her male co-stars all looked dapper in tailored suits. They were joined by other stars like Aaron Johnson, Elizabeth Olsen, Paul Bettany, and director Joss Whedon at the Westfield London for the European premiere.

The superhero movie has hit international theaters but will not arrive in North America until May 1. It will be Whedon's last "Avengers" movie after he directed the first two installments. The next entries "Avengers: Infinity War Part I" and "Avengers: Infinity War Part II" are set to be helmed by Anthony and Joe Russo.

"Yeah it's sort of like sending your kid off to college, it's like wow, they really don't need me anymore, do they?" Whedon said on the red carpet. "At the same time it's like, 'My kid's gone, party all night!' You know, I'm going to pick my actual kids up from school, I'm going to read books, it's going to get crazy."
