6. Do some self-deprecating comedy.
Katie's sub-par supporting role as Adam Sandler's wife in Jack and Jill made for painful viewing, not only because it was entirely implausible that Sandler would ever land someone who looks like Holmes, but also because the script was godawful. Yes, Katie, we're blaming it on the script. You can thank us later.
Sandler's storytelling shortcomings aside, we also have a strong suspicion that Holmes is taking herself too seriously. Her next comedic role should focus on more darkly comic material—her personal life.
Considering James Van Der Beek is in the midst of a quasi-comeback thanks to taking cracks at Dawson's undeniable douchiness on Don't Trust the B---- in Apartment 23, Katie should follow suit by taking a swing at her unfolding Scientology saga on Saturday Night Live. SNL has long been the preferred comeback vehicle among fallen stars (see: Lindsay Lohan), and we bet that if Katie could tossed some well-timed snark in her own direction, people everywhere would once again find themselves fawning over her.
