Despite the fact that Sherie Rene Scott was 35 when she played Cathy, the character shouldn't really be more than mid-to-late twenties. (Lauren Kennedy was 28 when she originated the role). When the story begins, Jamie is 23 (as alluded to in the lyrics of "Moving Too Fast": "got all this and more / before twenty-four") and Cathy should be in the same age range (23-2. Kendrick is 27 as of today; I'd say as far as age is concerned, she's ideally cast.
According to Deadline, Sherie Rene Scott's husband Kurt Deutsch is among the film's producers. Interesting. I wonder if he's tied into the licensing rights for the music because of his work with the original cast album.
