I read the book too long ago to remember too many details (its on my re-read list) but I've seen the movie more than a few times and thought it was really good. Al Pacino was fantastic, and Johnny Depp and Michael Madsen were great as well (they're both so under rated). Anyone who doubts Depp's acting ability should watch this movie or Blow in which he which he gave arguably an even better performance. I give D.B. an 8 out of 10.
