I have been watching BoyHood over the last couple nights...
...and I have really come to admire his skill as an actor. I think about how hard it must have been for him to "act" like he was living his everyday life. For example; when his stepdad starts to become abusive due to his alcoholism. He couldn't be dramatic and "act" like the whole world was falling apart, even though, in many ways, for his character Mason it was. About the only time he gets is a few seconds of a tight focus camera on his facial expression. In that time Ellar has to convey all the emotions that Mason is probably feeling, but is really powerless to change. Imagine Ellar trying to convey Mason's feelings about losing his two "siblings" that he loves and are his friends in a two minute scene. He acted out what most everyday boys would do; he went with his mom, went to his new school, and tried to carry on. What I have not seen yet is if this will effect Mason in the future.
What I find fascinating is that this movie was actually filmed during Ellar's own growing up years. The bold directing decision to keep the same set of actors and use them as the years passed was brilliant. To my knowledge this has never been tried in films before. I enjoyed watching him change and grow as the movie progresses. I actually came to IMDB to see if it really was the same actors. So far I am really impressed, and the film is definitely living up to its advertising.
This post is getting too long or I would describe what an incredible job of acting Patricia Arquette has done so far as well.
