The hugely popular revival of Doctor Who is coming to Sony's PlayStation Portable.

2Entertain, the music-to-movies company jointly owned by BBC Video and Woolworths, said last week it plans to release three episodes of the recent terrestrial TV ratings winner on the PSP's UMD format later this month.

The new series was released on DVD earlier this year. The first UMD release is actually the second batch of epiodes, but since the disc contains hit story Dalek, that's not an entirely surprising choice. The other episodes are Aliens of London and World War Three, which both see the Doc battling human skin-wearing 9ft-tall monsters afflicted with bad wind known as the Slitheen.

UMD version of DVD volumes one, three and four - the latter featuring the Skaro war machines' second appearance in the series - are set to ship in December.

Ironically, in episide 12, Bad Wolf, the Doctor finds himself in Earth orbit aboard the "Game Station".

All four UMDs will retail for £18, though like the DVDs, we expect they'll be heavily discounted by online suppliers.

In the meantime, fans are eagerly awaiting the monster series one box set, which contains the series' 13 episodes all with newly recorded cast and crew commentaries, plus a fifth disc full of extras, including video diaries, interviews, making of... documentaries, behind-the-scenes details, not to mention a trailer for the upcoming Christmas Invasion.

The box set - yes, it's Tardis shaped - is due to ship 21 November for £50. ®
