Update. I love it when I question some detail a writer I like has possibly gotten wrong and I turn out to be the one who is wrong. The situation came up in The Kite Runner when the author made reference to Pacino's accent Godfather I and I figured he had to mean Brando. The following is from graypanther on another site:

In answer to the query posed above... Mr Pacino did in fact have a distorted speech pattern for part of the movie. It was caused by Sterling Hayden punching him in the face quite visciously when Michael thwarted their attempt to assassinate his father at the hospital. He also drooled uncontrollably for some time after the incident.

I sit* corrected.

*Bit of wheelchair humor there.
