"... Tilda Swinton is wasted in a thankless role ..."?!?
The Hollywood Foreign Press Association decided that she was good enough to be nominated for a Golden Globe for her work in this film.
The prestigious British Academy of Film and Television Arts decided she was good enough to bestow her work with a BAFTA Film Award.
And the holy grail of film acting, the Academy of Motion Picture Arts and Sciences (where her own peers vote for the award) decided to give her an Academy Award for Best Performance by an Actress in a Supporting Role!
On top of that, nine other industry and/or film critics associations deemed her work worthy of - at the least - a nomination.
So, the question remains, what did Mr. Gaita do while he was watching the film? Was he distracted by the phone, or maybe popping some popcorn? I'm just curious!
