It seems that Disney is very pleased with what they have seen from Joseph Kosinski's "Tron Legacy" that they are planning a sequel. While the movie will not be released in U.S. theaters until December 17, the studio has been reported developing the follow-up.
According to The Hollywood Reporter, "Lost" writers/co-executive producers Edward Kitsis and Adam Horowitz who have also penned "Legacy" are hired to write the sequel. There has been no further information about the project because it is still in early process, but insiders have suggested that Disney wants "to round the story into a trilogy" with "Legacy" as the beginning.
No deals have been made with director Kosinski as well as the cast members although options to return to the sequel have been included in the original deals. The helmer himself has previously claimed he is not interested to be known as a studio-sequel/remake director.
"Tron Legacy" itself is a sequel to 1982 "Tron". The upcoming release will follow Sam Flynn as he investigates the disappearance of his father Kevin Flynn and finds himself pulled into the same world of fierce programs and gladiatorial games where his father has been living for 25 years. Garrett Hedlund stars as Sam while Jeff Bridges reprises his role as Kevin.
