When Donnie Darko was released in 2001, it became an instant classic. The surreal psychological drama starring Jake Gyllenhaal, Jenna Malone, Drew Barrymore and Patrick Swayze centers on a young man (Gyllenhaal) who is suffering under the weight of massive existential angst in his suburban hometown, which comes to mean hallucinations of a threatening figure in a bunny suit who warns him of the end of the world, mysterious plane crashes and more. Donnie Darko grossed $7.3 million — nearly twice its small budget — and if the dark themes about the dire state of the world we live in hit home 15 years ago, they’re only going to have more of an impact today. Watch the film with its director and writer, Richard Kelly, at 9:30 p.m. Saturday at the Alamo Drafthouse, 100 South Central Expressway, Richardson. Tickets are $15 at drafthouse.com.
