Malcolm Tucker is the fictional, foul-mouthed political enforcer from the British comedy The Thick of It played by Peter Capaldi (doing a recent turn in Torchwood's Children of Earth as the tortured senior civil servant Frobisher).

I only know Alan Cumming from watching one of the X-Men movies on the plane with the sound off, and also having him pointed out to me at a Zadie Smith book reading. And wasn't there some mock cologne commercial that he did? So the comparison to Malcolm Tucker is more based on how the role in The Good Wife is written, plus incidental Scottishness on the part of the actors.

Nice to see you! I read your posts avidly, even if I'm mostly comment-shy these days. ;)
