Chuck Todd makes ‘Maddow’ appearance … sort of

With NBC’s Chuck Todd no doubtably burning the candle on both ends for the past few weeks, it wasn’t surprising he wasn’t able to make it for Thursday’s “Rachel Maddow Show.”

So, Maddow decided she’d “take” Chuck’s place by keying a live shot of her own head over a shot of Todd taken from election night coverage footage. It’s an interesting effect that appears to be accomplished with chroma key (rather than just cutting around Maddow’s head and placing it over Todd’s).

If this is the case, where did the chroma key background come from? We’re guessing (and this is just that — a guess) that chroma key green or blue was projected on to one of the RPs in the MSNBC studio.
