Doctor Who's Steven Moffat has confirmed that Matt Smith's future with the show is still unclear.
At a press conference this morning (March 21), the showrunner told journalists that the 29-year-old actor "hasn't made up his mind" about how long he will stay with the sci-fi drama.
"Honestly we don't know [how long he'll stay]," said Moffat. "We take it a year at a time and that's the only sensible way you can go with it."
He added: "It takes a huge amount of time, filming a series of Doctor Who and towards the end of that, you have to consider whether you're going to push on to another one."
Moffat added that he is keen to have Smith remain with the series for the foreseeable future.
"The honest answer is, we don't know," he admitted. "We'll keep him as long as we can, that's the absolute truth."
Jenna-Louise Coleman (Emmerdale) was today unveiled as the new companion to Smith's Time Lord.
The 25-year-old actress will debut in the show's 2012 Christmas special, replacing outgoing stars Karen Gillan (Amy Pond) and Arthur Darvill (Rory Williams).
