Actress Scarlett Johansson wants to follow in Brad Pitt's footsteps and establish herself as a versatile actress.

In an attempt to explore more avenues, Johansson gave her voice to the operating system named Samantha in the Oscar-nominated film "Her".

"If you want to grow out of the stereotype the media stamp on you as an actor you have to focus on challenging yourself and taking on diverse roles. Brad Pitt has managed to do that. While he has always been regarded as 'so gorgeous' he has never let that prevent him from being a character actor, which is what he is and what I have always wanted to be," Johansson said in a statement.

The 29-year-old says she would prefer to be known as a character actor than be classified as the romantic comedy queen.

"There is nothing wrong with an acting career in which you play the romantic lead or America's sweetheart or the romantic comedy queen, but I have never thought of myself as playing those kinds of roles. I have always wanted to be a character actor," she added.

"Her" releases in India Friday.
