21. Cooper was supposed to have more of a romance with teen temptress Audrey Horne, but according to Sherilyn Fenn, Lara Flynn Boyle—who played Laura Palmer's BFF Donna—was dating MacLachlan and didn't want him sharing all that screen time with Fenn.
"What happened was that Lara was dating Kyle, and she was mad that my character was getting more attention, so then Kyle started saying that his character shouldn't be with my character because it doesn't look good, 'cause I'm too young," Fenn told The A.V. Club in 2014. "Literally, because of that, they brought in Heather Graham—who's younger than I am—for him and Billy Zane for me. I was not happy about it. It was stupid." (Without naming names, Mark Frost had told a version of this story in 2011.)
22. Fenn was one of many actors in her age group that Lynch chatted with for potential roles, and she ended up with a part tailored for her. "It was the first time I'd ever actually been myself in an interview and tried to just be open," she told The AV Club. "But it went great, and they called and said, 'Yeah, he's writing you this role!' When I got the pilot, a two-hour script, it seemed like nothing, but I don't know. David's just kind of a wizard. He sees things in certain people and knows how to weave them into a story."
(Alas, she didn't really tie a knot in a cherry stem with her tongue.)
