R.I.P. William Russell, 99, from "Dr. Who" (1964)

See the short thread, here....

Does anyone here already know what his son, Alfred Enoch, is famous for?
(grin)
Quite a connection between two very different sf/fantasy worlds!
Anyway, I'd appreciate it if anyone could answer the question I raised,
in the thread, about the missing serials from the 1960s. (Namely, since
Louis said "At least there are not as many missing as there once were,"
I'm curious as to whether any have been FOUND in the last 35 years or
so.)
