Doctor Who Stars Tease The Rings Of Akhaten
Matt Smith and Jenna-Louise Coleman discuss this weekend's episode...
Following last week's The Bells Of Saint John - which saw the show return after a long mid-season break - the Doctor and his new companion leave Earth far behind for a colourful alien world.
"It's kind of epic and huge and moving and funny and heartbreaking and kind of just big," said Jenna-Louise, who plays Clara Oswald in the hugely popular sci-fi show.
"It's the first time Clara gets to experience what the Doctor can offer her and what life would be like travelling with the Doctor.
"The colours and the aliens and the buzzing kind of world around her."
And Matt Smith adds: "Having had a sort of modern day urban thriller we then go back into space and time and to the future.
"There must have been 50 or 60 alien heads, different kinds of prosthetics. It's days like that that you go 'wow, I'm making Doctor Who'."
The Rings Of Akhaten will be screened this Saturday at 6.15pm.
Smith was pictured with former Doctor David Tennant at a read-through for the show's 50th anniversary special recently.
