The new, "more deadly" breed of the Cybermen, who are out to convert humanity to their own kind, will feature in the first two-parter of series two.
"The villainous Cybermen are as much a part of Doctor Who heritage as the Daleks and so it's a huge personal thrill to see them back," said show producer Phil Collinson. "I hope that the evil silver giants will terrify a whole new generation of viewers as they confront the tenth Time Lord."
The monsters first plagued the Doctor in 1966 and were last seen in 1988.
