Ah! Decades-old spoiler alert!
Mark Hamill may have spilled the beans about his iconic Star Wars character years ago while doing an interview with the late film critic Gene Siskel around the time Return of the Jedi was released.
In the unearthed interview, Hamill said George Lucas explained to him his layout for the prequels and also told Hamill to be ready, because he had plans for Skywalker many years down the road.
"George has talked to me very marginally about doing something at the turn of the century in the last trilogy, but it wouldn't be on the same plane of existence," a young Hamill explained to the Chicago Tribune journalist.
Siskel cut in, "What it sounds like is he offered you a job to play a father [with] a Luke Jr. around the year 2000."
Shaking his head in agreement, Hamill replied, "You're a very clever man, Mr. Siskel."
There's been endless speculation about Rey's (Daisy Ridley) parentage in the new trilogy, with Luke put forward as a prime candidate for the role of her father. Lucas is not involved with the new trilogy, having sold Lucasfilm to Disney in 2012, but he did share his story plans with the new owners.
Director Rian Johnson wrote the script for The Last Jedi, and though the story has likely completely changed since Hamill gave the interview decades ago, it is still fun to mull over the possibilities of Luke being a dad.
Hamill starts talking about the future of Luke at 7:55 in the video below.
The Last Jedi is due out in December.
