Will Smith shaped his acting career by playing the relatable "good guy" roles in blockbusters like Men In Black, Independence Day and I Am Legend. So when he hopped on for Suicide Squad, a film filled with DC Comics antiheroes, the move was unexpected. The actor explains his decision to play Deadshot to Entertainment Weekly:

“I had never played a character that legitimately didn’t give a fuck. It’s very freeing not having to carry the moral spine of the movie. I couldn’t find a model to understand what would make someone comfortable killing another person for money. David [Ayer] walked me through that. He found a book for me [The Anatomy of Motive by John Douglas], and I worked through getting into the mind of serial killers. Once I accepted the [notion the author puts forth] that it feels good, that really exploded the idea in my mind of Deadshot.”

While Smith stepped out of his comfort zone to play an expert assassin, there is one trait Deadshot has that he can relate to. The actor, who is the father to 15-year-old Willow Smith, says about the character:

“His Achilles heel is his daughter. He loves this little girl and that creates this bizarre conflicting mindset where he enjoys killing people but that’s something this little girl doesn’t want from him. She wants a daddy.”

Suicide Squad is due in theaters on Aug. 5, and also stars Margot Robbie as Harley Quinn and Jared Leto as The Joker. Be sure to check out our complete guide to the film ahead of its release.
