Empire Online looks into the story about why and how a sequel to Disney’s Tron is now finally getting made nearly 30 years after its original release. Declared a flop when it first came to theaters, the revolutionary Tron gradually gained a large fanbase over time, causing the Mouse House to eventually take notice. A trailer for the sequel, currently playing on the big screen with prints of Alice in Wonderland, can be found here. The movie is due in theaters this Christmas.
