Smith 'teases scary Who monsters for US eps'

Matt Smith has promised that the upcoming US-filmed episodes of Doctor Who will feature the scariest monsters yet.

During an interview for the Nerdist podcast, the actor admitted that he was terrified by the villains that were created for the sixth series.

"The ones we've come out here [to the US] to film... I think the monsters are on par with the Weeping Angels," he said. "It's the most hideous thing in the world."

Smith also suggested that comic legend Peter Sellers would have been a terrific choice for the role of The Doctor during the early years of the BBC One show.

"He'd have been amazing. He'd have been really, truly brilliant, I think," he explained.

Smith continued: "[He] totally has a coldness about him… I think the darkness of Sellers would have been really interesting."

Doctor Who returns for a special one-off episode at Christmas on BBC One in the UK and BBC America in the US, while the sixth series is to follow in the spring of 2011.
