Sadie Stanley's very first acting role saw her bringing an iconic cartoon character to life. She was tapped to play Kim Possible, the spunky teenage super-spy and star of the early 2000s Disney Channel show of the same name, in a 2019 live-action reboot. The movie aired on the Disney Channel and was followed by a miniseries titled Kim Hushable, which saw Kim and her friends tackling a new adventure while on spring break.

Kim Possible wasn't just Stanley's first acting role — it was also the first time she ever auditioned for a part. The actress wrote an essay about her young career for Backstage, in which she talked about her lightning-fast journey from catching the acting bug to starring in her own movie. Of the Kim Possible audition, she said, "The role felt completely out of my league and I was shocked yet so excited that I could even get in the audition room, considering I had literally nothing on my resume. I went in to the audition just hoping to do my best and have fun, with the thought that potentially nothing would come out of it."

Of course, something did come of it. "I had no idea that a year later I would be seeing myself on posters and commercials," Stanley said, "playing that same role that I thought I had no chance of getting."

While Kim Possible may have been her big breakout, Stanley quickly followed up that role with TV gigs that proved she wasn't a one-note performer.
