I am so glad you referenced Mitchell and Webb.
Have you seen the weird Channel Four trailers for some 'the event' programme? I think it was an NBC thing originally. That rather spoils my 'stole it from M&W' theory, but, hey ho.
Do you mean the ones for the remake of "V", with everyone staring up at the sky?
I think I mean this: http://en.wikipedia.org/wiki/The_Event_%28TV_series%29
Although I have just returned from Friday night post-work drinks, so that should come with a caveat.
Whoa, no, I haven't seen those yet... Jason Ritter. Heh.
