Nothing about Donnie Darko is normal or straightforward or easy, from its use of time travel to its more expository Director's Cut to the impactful-if-confusing ending for all the characters. Though Jake Gyllenhaal's titular hero...ish figure and his rabbit-eared hallucination have remained icons of cult cinema for 25 years now, Richard Kelly's attempts to craft a sequel went unrealized for years. But that all changed in the most massive of ways, as Kelly has an official sequel on the way, and plans much more.
As much as I'd love to giddily blurt out as many details at once as possible, it's probably easier for everyone else to understand if I lay Richard Kelly's Donnie Darko plans out sequentially.
