Speaking at the TV Guide Magazine Fan Favourites' panel at San Diego Comic-Con today (July 14), the actor revealed that the series's first episode 'Asylum of the Daleks' would be broadcast some time in August.
The confirmation comes after news that the episode will be given a public premiere at BFI Southbank in London on August 14, while it will also be screened at the Edinburgh International Television Festival, which takes place from August 23 to August 25.
Series six episode 'Let's Kill Hitler' was given its first showing at the Festival last year and broadcast on BBC One the following day, with Smith's revelation suggesting that this may also be the case with 'Asylum of the Daleks'.
However, the BBC has yet to confirm an official air date for the new series.
New footage from the show is expected to be screened at the Doctor Who panel discussion with fans at Comic-Con tomorrow (July 15), with Smith to be joined on stage by Arthur Darvill and Karen Gillan, as well as producers Steven Moffat and Caroline Skinner.
