L is for Lars von Trier.
M is for Michelangelo Antonioni.
By the way, we forgot I, for Ingmar Bergman.

Right, I’m sorry!
O is for Otto Preminger.
P is for Pedro Almodóvar.
R is for Robert Zemeckis.
S is for Sergio Leone.
We forgot Q, for Quentin Tarantino.
T is for Terry Gilliam.
I was expecting to do that one!
U is for Unkrich, Lee. (I couldn’t think of anyone who had the first name starting with “U”)
I was torn between Sergio Leone and Stanley Kubrick 
Don’t worry, Unkrich is great.
V is for Victor Fleming.
W is for Wes Anderson (or Woody Allen).
I could only find one with X, Xie Jin, and I have no idea if he’s great or not, but it seems there aren’t many others.
Y is for Yasujiro Ozu.
Don’t worry!
Z is for Zack Snyder. Not exactly a great one, but I can’t think of any other with Z in the first name.
By the way, I’m looking the episode of The A.B.C. Murders (one of my favourite Christie novels) and it recalled me of this game)
So, the next category will be fictional detectives.
A is for Adrian Monk.
To make this easier, this can be either the first or the last name.
Oh, nice category!
B is for Beck, Martin.
C if for Charles, Nick (and Nora)
D is for Decker, Peter.
E is for Ellacott, Robin.
F: Flack, Don, CSI NY
