Many editions of this series no longer exist in the BBC archives, and are presumed lost. Among the editions which survive include "Talking to a Stranger" and "The Year of the Sex Olympics".
"Theatre 625" was so named to highlight the fact that it was on the BBC's new BBC2 channel, which broadcast at 625 picture lines, the "high definition" of the era, up from the older 405-line standard.
