Lisa Lynds had but one role to her credit—that of Emma in the 2005 straight-to-video drama Certain Women—when she was hired on to play Tiff in Mr. Gibb (2006), released in 2008 as The Good Student. But Lisa was bringing more than a skimpy résumé to the table: She also brought with her a willingness to show off her rack and to pull double duty as a hair and makeup assistant. That’s working hard for the money.
