This doesn't address Cebola's question....

I'm not sure where you're looking that doesn't show Director. 

On the Detail View (poster and lots of title info), Director(s) are included.

In Grid View, the popup information includes Director(s).

In the Export file, Director is a column exported.

And if you want to collect all such titles on a shorter sublist within IMDb, use Advanced Title Search, then

1. enter the director's name or name id into the Cast/Crew box (roughly in the center of the page), wait for the possible matches and select your person.
2. down near the button to launch the search, about a screen above that are the Include and Exclude boxes with all your lists. Select the List to Include.
3. launch the search.
