Meanwhile back in Zenda …
I watched a free YouTube copy of the Prisoner of Zenda 1922 silent film version (speeded up on the right corner click replay to 1.5 / 1.75)
IMDB entry with crew list and trivia https://www.imdb.com/title/tt0013515/
Taster Clips of several film versions of Zenda exist, the 1937 ones onward seem to be available online or DVD. So you would have to buy them. Must track the Peter Sellars 1979 one down.
I could not find this 1922 MGM movie in UK playable DVD form so hopefully not infringing anyone’s copyright by watching.
One of several Youtube links to entire film (admittedly with adverts) https://youtu.be/3R_tWqVGwAk
