Not the oldest, but Dirty Harry (1971). I'll be adding more oldies in time!

EDIT: How could I forget "Pinocchio" ? :o = 1940

My two oldest movies are:
The Godfather - 1972 (part of the godfather collection)
Blazing Saddles - 1974

And maybe one day if it ever comes out on Blu-ray "Robin and the 7 hoods (1964)" will be my oldest.

Snow White and the Seven Dwarfs (1937)

Wow, I feel lame, my oldest film is '95, Toy Story.

Same for me, but it will be Metropolis as soon as it's released.

2001: A Space Odyssey (1968)

Dr. No, From Russia W/ Love, Goldfinger, etc.

I love Sunrise! I had no idea it was available on BD!

Oldest ten:

The Wizard of Oz - 1939
Black Narcissus - 1947
The Searchers - 1956
Jailhouse Rock - 1957
Dr. No - 1962
From Russia with Love - 1963
The Leopard - 1963
The Pink Panther - 1963
Viva Las Vegas - 1964
Goldfinger - 1964

My BD collection would ideally consist of mostly 1930s to 1970s films.

Looks like it's Sherlock, Jr. (1924) for me.

Snow White and the Seven Dwarfs (1937), but like others have said, the Metropolis release coming soon will change that for me.

I thought Sherlock, Jr. wasn't out until November?

Don't have many old ones.

Wall Street (1987), Die Hard (1988), T2 (1991), Reservoir Dogs (1992). Those are the oldest blus I own.

I'm only 20 (21 tomorrow!), and I've never gotten into too many older movies.
