Just a few trailers of "writer films" I've liked over the years, in no particular order:
Midnight in Paris, 2011
The Rum Diary, 2011
Born Into This (Bukowski Documentary), 2003
A Love Song for Bobby Long, 2004
Big Bad Love, 2001
That's it for now. These are all definitely worth a watch. I'll add more as I remember them~there's quite a few out there!
