For the documentary, a film crew followed Brown for an entire year as he attempted to stage a comeback and regain his respect. Though I haven't seen this episode yet, the Inside (Out) that VH1 did on Warren Zevon was incredible, so I will definitely check this one out.
Of, if TV specials aren't your thing, you can remember the Godfather of Soul in song. I love this James Brown tribute created by DJ Bluewater using highlights from old, crackly 45s. (Thanks to Idolator for the tip.) Or, you can check out this great video homage.
