Lionsgate has announced that action comedy crime thriller "One For The Money" will be released in theaters on July 8th, 2011. The film, which is based on the best selling novel by Janet Evanovich, sees Katherine take on the leading role of former lingerie buyer turned bounty hunter, Stephanie Plum.

The movie, which is currently shooting in the Pittsburgh area, also stars Jason O'Mara, Daniel Sunjata, John Leguizamo, Sherri Shepherd and the most recently announced cast member, Hollywood screen legend Debbie Reynolds.

Katherine Heigl as Stephanie Plum

Reynolds will play the part of the feisty Grandma Mazur, the outspoken, outrageous advisor and maternal grandmother to Katherine's character.

"Grandma Mazur is such a great character," Katherine told Deadline. "She's really feisty and the one who's a real mentor to Stephanie Plum. We needed somebody for the part who would speak her mind and even be a little edgy. We approached Debbie Reynolds because she has that 'Molly Brown' as a contemporary grandmother. She's so perfect for the part. Then she read it, loved it and joined immediately."
