From the Guardian's review of Grace of Monaco, starring Nicole Kidman -- "a film so awe-inspiringly wooden that it is basically a fire-risk":

Then, in order to bone up on the history and culture of Monaco — and perhaps because the situation is not yet sufficiently gay — Grace consults a local nobleman, Count Fernando D'Aillieres, played by Derek Jacobi. He scampers about the hillsides, with Grace in tow, filling her in on all the tiresome details, while also presuming to give her tips on acting and deportment. (Surely as an Oscar-winning star she knows this stuff already?) Jacobi has a little fun with the part, although it needed Ian McKellen to come on, playing the Count's ageing houseboy.
