Irma Theakston

Star of Kill Bill Part 1, Kill Bill Part 2 (two films - "how do we know Quentin? We paid twice"), Prime and The Accidental Husband. Mark believes her to be somewhat wooden - specifically, she "makes Ikea Knightley look like Dame Judi Dench."

It's a shame in that case he didn't go for "Irma Teakston" instead, but never mind.
