Forest of the Dead preview

Thanks to Kasterborous for this Forest of the Dead preiview:

The second part of the adventure that kicked off with Silence in the Library sees the Doctor trying to rescue Donna and figure out just what the hell is going on in Forest Of The Dead, this Saturday at 7pm, BBC One.

As the shadows rise and march, the Doctor forges an alliance with the mysterious River Song - but can anyone stop the Vashta Nerada?

While the Doctor discovers long-buried secrets and revelations about his own future, the sinister Nodes declare that Donna is doomed.

Newsround's outgoing Doctor Who fan Lizo (bye Lizo, thanks for the unbalanced reviews!) says of Forest of the Dead:

The Doctor, devastated at losing Donna, knows that if they're going to survive he needs to solve the mystery of what the little girl has to do with the Library. But he also wants to find out what his relationship with River Song is.

Where the first episode was terrifying, this story has a much more eerie atmosphere, as it gradually becomes clear what's really been happening in the Library.

David Tennant plays the Doctor and Catherine Tate plays his companion, Donna Noble. Guest staring are Alex Kingston as River Song, Colin Salmon as Dr Moon, and Steve Pemberton Mr Lux.
