No matter what side of the fence you fall on when it comes to Quentin Tarantino, I don't think one can argue with the pleasure that comes from seeing which old(er), familiar faces from the past the filmmaker will resurrect next. With Django Unchained, there is no shortage of cinema greats and near-greats from years gone by. Perhaps most exciting was the "friendly participation" of original Django Franco Nero. We get the likes of Don Stroud, Russ Tamblyn, Don Johnson, Lee Horsley, Robert Carradine, Tom Wopat, Michael Parks, Bruce Dern, Cooper Huckabee, James Russo, and the list goes on.
I personally most loved that Tarantino used two of my favorite actors from two of my favorite films of 1979 or any year...Dennis Christopher of Breaking Away and James Remar (in 2 roles!) of The Warriors. Breaking Away may not be part of the official gang cycle of that year (Warriors>Wanderers>Over The Edge>Boulevard Nights>Walk Proud), but it did focus on a group of pals...a gang of sorts, albeit a non-violent one. Anyhow, I imagine Tarantino had this in mind, to a degree, when he cast Christopher and Remar.
