Edie McClurg may be the ultimate character actress.

Before getting into movies, she joined the renowned Los Angeles Groundlings improv troupe and did stand-up at the Comedy Store, back when David Letterman was just a no-name emcee.

Improv led to her getting cast in her first film, 'Carrie,' alongside Sissy Spacek. But McClurg is probably best known for her work with director John Hughes, particularly in 'Planes, Trains and Automobiles' where she has some choice words for Steve Martin, and as Grace, the high school secretary in 'Ferris Bueller's Day Off.'

As 'Ferris Bueller' celebrates its 25th anniversary on Saturday (wow, right?), Moviefone talked to McClurg about the movie's timeless appeal, what scenes were improvised and which jokes made John Hughes laugh the hardest.

Turns out, she's a righteous dude.
