'Tron: Ares' Stars and Director Explain How That Unexpected End-Credits Scene Sets Up 'Tron 4' [Exclusive]

Editor's Note: The following contains major spoilers for 'Tron: Ares.'After a grueling 15-year wait for fans, Tron: Ares is finally here, and it brings with it one doozy of an ending. Within about a half an hour, we get to see a Recognizer lay siege onto a human city, the grand return of Kevin Flynn (Jeff Bridges), and even get a very big hint that Ares (Jared Leto) is now trying to find Sam Flynn (Garrett Hedlund) and Quorra (Olivia Wilde) after they went off grid (so to speak) after Tron: Legacy. The latter development undeniably plants the seeds for a potential Tron 4. However, perhaps the biggest hint towards a potential sequel comes during the film's mid-credits scene, which shows a now imprisoned Julian Dillinger (Evan Peters) finding an older identity disk that seemingly transforms the villainous CEO into a reincarnated version of Sark — the main antagonist of the original 1982 Tron film played by David Warner (who also plays Julian's on-screen grandfather Edward Dillinger as well as voices the Master Control Program in the 1982 movie).
