Denzel Washington: usually in pretty good films. Training Day - ace. American Gangster - ace. The Manchurian Candidate - ace.

Chris Pine: usually pretty good in films. Star Trek - ace. Er, yup.

Rosario Dawson: usually pretty good in films. Sin City - ace. Okay, great.

So, Unstoppable, bits of which ACTUALLY HAPPENED (press release: “inspired by actual events”), sounds like it might be similar to Speed (press release: “race against the clock to stop an unmanned runaway train”) but that's okay because Speed was good.

Unstoppable is in cinemas on November 24.
