Dr Stuart Lee states in his 3rd June 2015 talk, that additional footage of Tolkien has been found from what was recorded in the 1968 Tolkien in Oxford BBC TV program (, an additional 1 hour 30 minutes.

Any suggestions on how we can get to view this footage, the BBC will own the rights to the material?

I am making the assumption that the additional material is from Leslie Megahey, the producer of the BBC 1968 Tolkien in Oxford program, but may be wrong.
