This is a good point. In theatre, to effectively play a lead, one must project the character's personality -- that is to say, exaggerate it for those not in the front row seats. Before a camera, this may come across as OTT. But the best film actors I can think of offhand are grounded in theatre, and return to it regularly. This is what you may call charisma.

We got around to the original, Richardson version a couple of weeks ago. Turns out we had watched previously, many moons ago on the old CRT tv set. For whatever reason I hadn't remembered the name so did not connect it to the more recent, USian remake -- apart from bad boy Kev's unplanned intervention, a fairly faithful rendition of the main themes and plot points. Mrs.D tells me some aspects of which are 'loosely based' on Hamlet and Macbeth.
