Some mild spoilers. Nothing serious though.....
Peter Sellers died in 1980 and yet two more Pink Panther movies were made with his character being absent yet integral to the story. The audience felt cheated by this cheeky ploy by the studio to cash in on his name... The first 30 minutes of The Bourne Legacy feels like that. Matt Damon declined to return as Jason Bourne and so this film continues where 'Ultimatum' left off and his character is listed as missing. Jason Bourne has fallen off the grid and the threat of public exposure forces the US Secret Defence Department to shut down the entire Black Ops program. This of course means killing all "participants" including Aaron Cross played by Jeremy Renner. He narrowly avoids assassination and finds himself on the run with a geneticist (Rachel Weisz) who is the only person able to help him maintain his enhanced physicality without meds. I think this is a clever way to continue the series. Rather than starting over with a new character and storyline, they have kept Jason Bourne's disappearance relevant to the plot with a manhunt for him still in effect. The whole Black Ops debacle is spiralling out of control and it's fallout is spreading. This makes for an interesting structure and its conceived with total credibility. For a lengthy film it moves along at a furious pace and never relents. Much like the previous movies it involves a string of elaborate chase sequences (some overlong) that force the viewer to forget that the structure is basically the first film all over again. Edward Norton, Stacey Keach and Rachel Weisz are welcome newcomers joining an ever-growing list of return players such as David Strathairn, Scott Glen, Albert Finney and Joan Allen. I'm keen to see where they go with the inevitable 5th instalment... all signs point to a Damon/Renner double team.
