Friendship is friendship and a wonderful thing
One of my favorite movies currently is showing on Encore on On Demand--"American Buffalo" . It's based on a David Mamet play. Dustin Hoffman and Dennis Franz have a great rapport, and the dialogue is beyond belief.
Of course, another great Mamet adaptation, and one that is better known, is "Glengarry Glen Ross", for which Al Pacino received a nomination for Best Supporting Actor in the same year in which he won the Oscar for Best Actor for "Scent of a Woman." Arguably, the academy gave the nod to Pacino that year to make up for all the years in which he was overlooked, akin to Paul Newman getting the Oscar for "The Color of Money."
