There’s one of the many Romola Garai nude scenes from the BBC Two miniseries, The Crimson Petal and the White.
Other than this show, she also appeared naked in Angel in which we saw a bit of the British actress’ ass from behind a chair. Before that, we kinda saw Romola Garai naked in I Capture The Castle. I say “kinda” because while she’s wearing no clothing at all, she’s covering up all of her private parts, so technically speaking, there’s no nudity on screen. There was, however, a bit of nudity on screen in The Incredible Journey of Mary Bryant, where we see Romola Garai nude during a somewhat brief yet totally satisfying sex scene.
