From Playmate to up-and-coming actress, Miss May 2009 Crystal McCahill will be turning heads in the Sin City sequel. The second-generation Playmate plays a sultry waitress in Sin City: A Dame to Kill For, starring Bruce Willis, Jessica Alba, Eva Green and Joseph Gordon Levitt.

Look for the brunette Playmate serving up shots to award-winning actor and professional boxer Mickey Rourke in the film.

Rourke starred in the first Sin City in 2005 and plays the hardened ex-con Marv. “It was really intimidating working with him,” McCahill said about filming with Rourke. “But he is so nice and super fun. He kind of stays in character the whole time.”

Directed by Frank Miller and Robert Rodriguez, the film has stirred up some controversy. In some promotional movie posters actress Eva Green apparently showed a little too much skin for the Motion Picture Association of America. The provocative movie posters were banned from being used. The trailer for the second Sin City shows the film to be dark and sexy, following in the footsteps of the original. McCahill’s look and personality are perfect for the film.

The sequel hits theaters August 22.

Miss May 2009 also appears in the comedy Flock Of Dudes, set to be released sometime in 2014 with costars Hilary Duff and Hannah Simone from New Girl. It’s evident this is just the beginning for the Playmate in Hollywood. “I love to do comedy. It’s a lot of fun,” McCahill told Playboy. “I really love to do anything, and I love acting.”
