What was the first silent film あなた ever saw?

Nosferatu (1922)

I am not completely sure but I think it was The Thief of Bagdad starring Douglas Fairbanks.
It is one of my all time favourite movies.

If memory serves me correctly, it was either Nosferatu または The ロスト World.

hmmm that was a ways back i believe it was Phantom of the Opera,or possibly Nosfuratu, または The Hunchback of Notre dame, it might of been a old cartoon real または Matropolis
but I'm almost positive it was phantom of the opera または one of Lon Chaney's films in genral
