I, Robot - Channel 4

It's 2035 Chicago and robots are man's best friends - but cop Will Smith doesn't trust the shiny helpers

It's 2035 Chicago and robots are man's best friends - but cop Will Smith doesn't trust the shiny helpers.

So, when scientist James Cromwell dives to his death in an apparent suicide, Smith thinks that new hi-tech model Sonny (brilliantly played by Alan Tudyk) is a murderer, even though robots should be incapable of harming humans…

As a robot expert, Bridget Moynahan is also along for the ride in a nerve-wracking thriller with breathtaking action scenes, an ideal hero in Smith and seamless special effects.

And, refreshingly, the final outcome is not as predictable as it first appears.
