Viola Davis super excited to be part of the <em>Suicide Squad</em> cast

Los Angeles - Viola Davis is "fascinated" by her role in Suicide Squad.

The 49-year-old actress is to play government agent Amanda Waller in the Warner Bros film centred around the super-villain mercenary team from the DC Comics Universe.

Waller is a hard-nosed and pragmatic agent who is prepared to do anything to protect the US, the country that uses the criminals for black ops missions, and Viola cannot wait to start work on the film and "pick up a gun".

Speaking to website Nerd Report, she said: "I'm fascinated by her. I'm fascinated by her in this world of superhero-ness because she is not a woman that you would expect."

Fans of the actress can not contain their excitement for upcoming film either as they took to Twitter to express their joy.

I think that she is a massive contradiction. "She's this big powerful black woman, hard, ready to pick up a gun and shoot anyone at will. I'm fascinated in exploring her psychology, just put it that way. And I'm excited to pick up a gun."

Suicide Squad has an all-star cast with Jared Leto playing The Joker, Margot Robbie as his sidekick Harley Quinn, Tom Hardy as Rick Flag, Will Smith as Deadshot, Jai Courtney as Captain Boomerang and Cara Delevingne as Enchantress.

Jesse Eisenberg is also said to be in talks to play Lex Luthor in the upcoming project, a role he will first take on in Batman v Superman: Dawn of Justice.

Suicide Squad which is being directed by David Ayer - is scheduled to open in cinemas on 5 August, 2016 and shooting is set to begin in Toronto, Canada, in April.
