Matt Smith thinks one of the monsters from the new series of 'Doctor Who' will "become a classic".
The actor - who plays the titular Time Lord - is looking forward to some of the new alien adversaries he and companion Clara Oswald (Jenna-Louise Coleman) will face in the forthcoming series, and is sure one of them will be considered one of the all-time greats.
He told Sfx.co.uk: "There's a new monster at the end of this season which I think will be a real classic. I'm always quite excited by the new monsters as well. They always tickle me."
It has already been announced the series will pit the Doctor against the Ice Warriors, a classic nemesis originally seen in the 1966 to 1969 era when second Doctor Patrick Troughton played the lead role.
Matt added: "I think it's always great to get the monsters that the fans love and can hark back to from the classic 'Who' series'. It's always nice to see them have a little revamp.
"We meet them on a submarine, which is even more exciting for the five-year-old in you, because they built the submarine, and they just literally flood it with water.
"It's a full length submarine, so it was really claustrophobic - and bearing in mind there's a film crew in there, and an Ice Warrior, played by a guy who's nearly seven foot tall. You couldn't swing a cat in there, let alone Jenna-Louise Coleman. And it was filled with water up to your knees, sometimes up to your chest. It was great fun, though. It was a right old laugh."
'Doctor Who' returns on Saturday on BBC One with 'The Bells of St John'.
