“She’s All That” changed Rachael Leigh Cook’s life. The 1999 teen romantic comedy — a modern-day retelling of “Pygmalion” — starred Cook as Laney Boggs, a homely, artsy outcast who transforms, in late ’90s parlance, into a “total hottie” and captures the heart of the high school heartthrob, played by Freddie Prinze Jr.

When the movie opened in theaters, it grossed $103 million worldwide, birthed a chart-topping soundtrack (thanks to Sixpence None the Richer’s “Kiss Me”) and made both of its leads into sought-after commodities in Hollywood.

It’s an experience Cook, now 40, looks back on with nostalgic fondness.

“I’m just grateful every day that I didn’t come of age in the era of camera phones, and yet, that makes me sound way more scandalous than I actually was,” says Cook, who started acting professionally at age 14.

But Cook still grapples with how to describe the formative years of her career.
