Fans will be lining up for Iron Man 2 regardless of whether or not the film airs a single advertisement.

The original installment in this franchise was arguably the best comic book movie of all-time.

So, how can the sequel top it? By casting Scarlett Johansson as a leather-clad ally of Robert Downey Jr's main character.

The latest issue of Entertainment Weekly features the first photo of Johansson in the role of Russian spy Natasha Romanoff, also known as The Black Widow. She's seen below alongside Mickey Rourke, who will portray Tony Stark's nemesis, Whiplash, in Iron Man 2.

The movie opens on May 7, 2010.
