MTV News sat down with Katherine Heigl at the "Killers" press junket in Beverly Hills a few weeks ago and spoke with her to get the scoop on new movie "One For The Money", which begins production in July.

Katherine's playing gorgeous but goofy bounty hunter Stephanie Plum in the film adaptation of the popular crime novel series by Janet Evanovich. In the interview she explained that finalizing her look was an important part of the production process:

Stephanie's a low-maintenance natural beauty ("a total jeans and t-shirt kind of gal so that's easy," said Katherine) - going out requires nothing more than a coat of mascara and some lipstick - but she's constantly dissatisfied with her hair.

"Stephanie, in the book, has brown, crazy curly hair that often is its own character," Katherine said. Getting the hair right will be a major part of establishing Stephanie's personality.

"I don't, obviously, have curly hair, so I think we're going to do wigs, because we're filming in Pittsburgh in the summer and its going to be hot and humid and I can't keep a curl", she added.
