Towards the end of the discussion at MetaFilter of the announcement about Bruce Willis, a delightful reminder of just how much fun Moonlighting was, back at its' peak.
As Mchelly put it: the "least-Bruce Willis-ever Moonlighting clip"
Bruce Willis may not have been a dancer by trade, but he was a professional who got the job done. That dance sequence was directed by Stanley Donen, goddammit! (It helped that Willis wasn't the one viewers were paying attention to in that scene, at least not for the bulk of it. Or perhaps that was just me…)
It may have come years before the current "golden age" of TV built up a head of steam, but in the good years Moonlighting was appointment TV.
