I guess they changed the title because of that Jason Reitman and Jennifer Aniston flick of the same name. At least this isn't just a sequel and/or unnecessary prequel Elmore Leonard wrote on a whim (i.e. "Be Cool") but actually vintage work of his.
I really enjoyed the chemistry between De Niro and Samuel L. Jackson in "Jackie Brown"...so hopefully some of it is replicated here with new actors in the roles (best case scenario).
My favourite line in the movie was, "What the fuck happened to you, man? Shit, your ass used to be beautiful". The context of the line and the way Jackson delivered made that a perfect movie moment.
