H-Day is upon us!

Yatta! Yes, as you're doubtlessly all too aware, the first season of Heroes launches tonight on BBC 2 at 9 o'clock. If it slipped your mind, however, consider this a public service heads-up, especially if tonight's going to be your first exposure to this multi-layered superheroic saga of cheerleaders and serial killers, geeks and politicians.

And it's a supersized serving of Heroes tonight too - the Beeb are showing the first two episodes and following them at 10.20pm with the first instalment of Heroes Unmasked, a behind-the-scenes documentary show.
