Spike actor James Marsters will be lending his voice to a character in the new animated series of Spider-Man.

Marsters will be providing the voice of the villainous Sergei, leader of Pterodax. Yes, we've no idea who he is, either.

The series, which is due to start on 11th July on MTV in the US, features Neil Patrick Harris as Peter Parker/Spidey and singer Lisa Loeb as the long-suffering Mary Jane. Rob Zombie stars as Lizard, with Virginia Madsen as Silver Sable and Michael Clarke Duncan as the Kingpin.
