Danny Boyle gives us a gripping story and James Franco gives us a believable role. We know what's going to happen but that doesn't mean we're not held in suspense. Perhaps it's horrendous to watch but it only lasts for one-tenth the time it happened in real life. True story well-told.
Q & A with director Danny Boyle:
How true were the video messages?
How and where was it filmed?
How did you choose James Franco?
How do you film something that really happened?
How did you work with the editor?
Was the storm sequence real or added by the scriptwriter?
