I think I would say 'The King's Speech' is surprisingly funny, in fact the audiences in London, Toronto, LA, New York commented there's more laughter in this film than in most comedies, while it is also a moving tear-jerker with an uplifting ending. ↗
The tension I feel is the moment they say, 'Action!' Movies are like lightning in a bottle, and you always want to find when you possibly can catch a surprising moment. ↗
