Collision, ITV1/The Execution of Gary Glitter, Channel 4

Carnage on the A12, and a long drop for Gary Glitter

The premise of Collision (as well as its title) is unmistakably similar to that of Paul Haggis's movie Crash, in which a road accident provides the linking point for a cluster of disparate personal stories. However, instead of the boulevards of Los Angeles, Collision exploits the less often remarked upon mystique of the A12, which links east London to Great Yarmouth. In 2007, the A12 was adjudged "Britain's worst road" in a survey by Cornhill lnsurance, so Collision's creator and writer Anthony Horowitz has picked an appropriate location for his fateful multi-vehicle pile-up.

Peep Show 6, C4

Flatsharing was never this funny

David Mitchell’s smarty-pants TV panel show ubiquity – over-exposure even by Stephen Fry’s standards - may have started eroding the goodwill built up over five series of Peep Show, but all is forgiven once he’s safely re-garbed in the horribly plausible, drab office-wear of nerdish flatmate Mark. It’s difficult to imagine any other comic actor giving quite the same defeated peevishness to the line: “A new boiler... surely the least enjoyable way to spend a thousand pounds.”
