Smith teases scariest who monsters ever

Matt Smith has promised that the upcoming series two part opener set in the US 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."
