Well, there is a whole mess of that.

Measured using Yuri Tsivian's Cinemetrics program, more or less in the order in which they were measured.

Next to last column is the average shot length (ASL) for the given film, in seconds.

Actual database is here.

Looks like they haven't been adding the director's name to the database since May-ish, so you can't do a full search by director at the moment. Also Dawn of the Dead is not an Italian film (though Argento did help finance it).

Okay, enough of that.

It is the weekend.
