what is the oldest movie you have ever seen?

I'm 24 and I've seen quite a few movies. Such as:

The Phantom of the Opera (Original) 1911

The Hunchback 1914

The Wizard of Oz (Original) 1939

The Giant Spider Invasion 1975

Hamlet (Original) 1948

It's A Wonderful Life 1946

The Nutty Professor 1963

Orphans of the Storm 1921

I had watched a lot of old movies I think The Great Train Robbery might be the oldest, it's from 1903. It was part of some old movies marathon/doc on tv, that was I think the oldest one they showed by I could be wrong. There was one with a train coming towards a camera, not sure if it was the same one, it could have been older.

Oh wait no they showed the first thing on film, it was a guy sneezing (I think). No idea how old that was and no idea what it was called.

The Passion of Joan of Arc-1928-a cieematically beautiful silent movie with the most expressive acting! I'm 28.

I'm 50 and the oldest movie I've seen is The Cabinet of Doctor Caligari made in 1920.

All Quiet on the Western Front (1930) is the earliest I know of. I watched it in history when I was a Freshman in high school (I think that was the class). I'm 35 now.

The Great Train Robbery, 1903.
