Here’s Kristen Bell on shooting a House of Lies scene where another character puts her foot in his mouth:
…it was as awkward as it seems to be.You know, I had just met another actor who, as per the crazy script written, needed to put my foot in his mouth. We talked about it and I washed my foot and he had a mint – just for shits and giggles – and we just kind of went for it. We didn’t practice it at all, obviously, because: No. 1) Why would you? That’s weird. No. 2) We wanted it to be realistically awkward when we did it.
