The London Mirror's review of the film lists the running time at 157 minutes. This site confirms it but minus 6 seconds:
I stopped by our two screen IMAX Theater here and talked to the guy in the box office about the running time. He confirmed that the platters hold a maximum of 150 minutes of film and was also curious about the print they are going to run.
A projectionist just happened to walk by on his way to work and we called him over. He told us that he's been told that the IMAX prints will be minus some minor footage that isn't essential to the audience's enjoyment of the film. He did not know how many minutes will be cut.
