With bleach blonde hair and a gravely disposition, Hollywood up-and-comer Saoirse Ronan tackles the role of a ruthless assassin in the movie “Hanna.”

The film follows the title character, who after being equipped with the right skills from her ex-CIA father, is sent across Europe to carry out a mission.

Starring box-office favorites like Cate Blanchette and Eric Bana, “Hanna’s” Ronan took the opportunity of working with seasoned actors to study their on set habits and techniques.

“Eric and I have this brother and sister relationship, we are always messing with each other,” Ronan said. “Cate is probably the most interesting one to talk about. She is really focused and professional, you can see that she really cares about what she does.”

The film’s director, Joe Wright, is no stranger to working with Ronan. The two teamed up previously on the Oscar-nominated film “Atonement.” Ronan scored an individual nomination for Best Supporting Actress for her role in the film.

“We had a great experience when we worked on ‘Atonement,’ we always had a really good relationship,” Ronan said. “He never treated me like a kid, even when I was 12 years old. I could see in myself that I had definitely grown as an actor, Joe noticed that too.”

Ronan was approached with “Hanna” long before the project had a director and suggested Wright for the job.

“Joe and I have this running joke now that I am the only way he gets jobs,” Ronan said.

Filmed across the bulk of Europe, “Hanna’s” scenes span the continent from Finland to Germany to Morocco.

“Every film that I’ve been in so far has been in really interesting locations,” Roanan said. “Everyone on set was excited to film in Morocco, but I had filmed there. I knew what to expect. It was the Sahara desert and it is a tough place to be.”

Citing acting inspirations like Uma Thurman’s the Bride in the “Kill Bill” series, “Hanna” was Ronan’s first action film.

Requiring an enormous amount of physical labor and training, Ronan was drawn to the physical challenge the film introduced.

“I always like to do something different,” Ronan said. “I’ve always been quite an athletic person so I knew that it would be both fun and tough work. It makes you really focused when you have pieces to learn.”

With a character as complex as Hanna, Ronan describes the character as “quite interesting and a bit weird.”

“It was quite important that I had to wipe my own memory,” Ronan said. “Hanna never really lived a life. I think it really helped to portray the innocence and naïve aspects of her personality.”

Drawn to the project by its script alone, Ronan describes what usually leads her to her latest projects.

“I love a well written script,” Ronan said. “I think I feel it in my gut when something is interesting and I am passionate about. I always find that if I read a script and catch myself thinking about it hours later, then it is something that I like.”

Receiving high marks from the bulk of critics, “Hanna” is well on its way to becoming the spring’s biggest box-office surprise.

With such high praise coming from the film, Ronan claims that a sequel hasn’t been ruled out.

“I think it would be really interesting to do a sequel, a lot of people have been asking me about it,” Ronan said. “I think if they were able to develop the character as well as they did in the first one, then a sequel would be great to do.”

“Hanna” opens nationwide Friday.
