Actors Frazer Hines and Tony Selby plus script editor and writer Eric Saward and visual effects designer Mike Kelt will be the special guests at the BFI screening of The Two Doctors.
The event, which takes place on Saturday 15th June to mark the Sixth Doctor's era, is the latest in the organisation's Doctor Who At 50 season and will start at 2pm.
The screenings have proved overwhelmingly popular, selling out as soon as tickets have been made available, although the BFI has introduced a ballot system to help make ticket allocation fairer.
Returns are always a possibility, though. As such, at the time of posting this news item four tickets were available via the event link. Stand-bys and other returns may also be available on the day.
