I had a nice and relaxed “Elsewhere Live” chat with screenwriter Guillermo Arriaga on Wednesday, 1.11. Arriaga is the gifted screenwriter of Tommy Lee JonesThe Three Burials of Melqui- ades Estrada (Sony Classics, opening wide in early February) as well as three films by Alejandro Gonzalez InnarituAmores Peros, 21 Grams and the forthcoming Babel. I’ll eventually put this into the “Elsewhere Live” archive, but here it is in the meantime. Arriaga spoke to me from his home in Mexico City.
