Genius, just about any decent biography of an interesting

really good director of photography. The Lord of the Rings Trilogy,
Hitchhiker's Guide to the Galaxy, and The Fifth Element. Ip Man,
Shaolin Soccer, and The Veteran. Following, The Boondock Saints,
and Pi. Primer, A Scanner Darkly, and Ong-Bak. Ghost in the Shell

Crowd, and the occasional bit of Battlestar Galactica.

bacon, pasta of any form, pizza, and New Mexican (bonus points if
you know the difference between that and Tex/Mex).
