The gurning in front of a camera: it’s like all of these actors, once transplanted into a role not far from home, feel like they need to behave like they’re in Don Giovani at the ROH, mugging away for the folk in the cheap seats, lest they lose any of the DRAMA.
they are all trained actors and if they did a 3 year course, acting for screen will have been part of it.
So, put it into practice, FFS.
