A video of the guest panel at last month's BFI celebratory screening of The Robots of Death can now be watched online.
The event, which was held on Saturday 20th April as part of the BFI's Doctor Who At 50 season, marked the Fourth Doctor's era.
The BFI has uploaded a four-minute excerpt featuring Tom Baker, which can be seen below and on its YouTube channel.
The fuller, 32-minute presentation, which also features former companion actress Louise Jameson and ex-producer Philip Hinchcliffe, can be seen here. The discussion was led by season co-curator Justin Johnson.
The BFI says it will be uploading the panel video from last Saturday's Fifth Doctor event next week.
As reported earlier, the next celebratory screening will be The Two Doctors on Saturday 15th June at 2pm. Because demand for all the events so far has been so high, tickets are now being allocated on a ballot basis.
