Here’s a new trailer for Tron Legacy, highlighting the disappearance of Kevin Flynn (Jeff Bridges), the protagonist of the original Tron film. Flynn’s son Sam (Garrett Hedlund of Troy and Eragon fame) receives a clue as to his father’s whereabouts and goes in search of the man he hasn’t seen in 25 years. What awaits him is beyond anything he could have imagined.

I must admit, I wasn’t too sure about this film when it was announced. However, if the visual style and atmosphere of the trailer is anything to go by, Tron Legacy looks set to be one of the most impressive and epic sci-fi blockbusters of recent times. Looking like the kind of film done a disservice when viewed on a small screen, it may well be worth shelling out a few quid extra to see it in 3-D at an IMAX.

Disney have released the first promotional poster for Tron Legacy, directed by newcomer Joseph Kosinski. The film stars Garrett Hedlund, mostly known for his supporting roles in films such as Troy and Eragon.

The main character is the son of the original Tron protagonist (Jeff Bridges reprising his role), who mysteriously disappears near the start of the sequel. This prompts a return to the cyber-world of the first movie, which has grown more spectacular – and dangerous – than ever before.

Tron Legacy will be released near the tail end of 2010.
