Mark Hamill outlined his appearance in next year's Star Wars: The Force Awakens back in 1983.
A British TV interview has surfaced on YouTube in which Hamill, then aged 32, talks about a conversation he had with Star Wars supremo George Lucas. "He, at one time, asked me, would you consider playing an Obi-Wan type character handing down Excalibur to the next generation?" Hamill goes into George Lucas impression mode, predicting that the film would come out "around 2011."
A trailer for 2015's The Force Awakens was released earlier today. The film is set around 30 years after the events portrayed in Return of the Jedi, and features original cast members as well as a new generation.
Luke Skywalker's actual story in the plot of the new movie is not yet known. Hamill was involved in filming scenes in Ireland in the summer, alongside Daisy Ridley, who plays a lead character.
