Sarah Shahi is having a Rocky time in Hollywood…

The 33-year-old half-Spanish actress, a guest star on NBC’s Chicago Fire and CBS’ Person of Interest, is adding a little sex appeal to Sylvester Stallone’s new action film Bullet to the Head.

“Acting with him was one of those moments in life that I will always remember and will say ‘Wow! I played Stallone’s daughter!’ He’s a generous, cooperative guy on the set,” says the former Fairly Legal star.

Shahi plays Lisa, whose kidnapping forces Stallone, in his role as a killer-for-hire, to take on a mission to save her and avenge the death of his partner.

Bullet to the Head, the first film in 10 years directed by action-film specialist Walter Hill, features a cast that includes Sung Kang, Christian Slater and Jason Momoa.

“Walter is wonderful. For him, less is more while shooting,” says Shahi. “He’s an old-school man of few words. He only gives orders when he deems it necessary. He likes his actors and loves what he does.”

Shahi, who grew up in Texas and became a Dallas Cowboys Cheerleader before pursuing an acting career, considers Bullet to the Head her most ambitious project to date.
