Dubbed “The Swedish Bombshell,” Helena Mattsson surely is making her mark in Hollywood. With a part in prime time’s hottest show, as well as 2010′s biggest summer blockbuster (so far!), Helena is no longer flying under the radar. I caught up with her recently to talk about Iron Man 2, working with Robert Downey Jr., and playing a gold-digging manipulator on Desperate Housewives.

Celebrity Extra: Iron Man 2 debuted at No. 1 its opening weekend and still dominates the box office. It’s well on its way to becoming Summer 2010 biggest blockbuster. This all must be very exciting.

Helena Mattsson: Very exciting. It’s just a really fun movie that I am so glad I got to be involved in. I saw the first movie and I really liked it. I was really excited to be part of this one. I have a really small role, but that doesn’t matter because it’s an appealing thing.

CE: Tell me about your character, Rebecca.

HM: I can’t say too much (to not give anything away for those who haven’t seen the movie yet), but I’m playing Rebecca, and I have this one big party scene where I sort of challenge Iron Man with his weapons, and there’s a lot of crazy stuff going on. I throw stuff up in the air. It’s a really big, crazy party scene.
