I don't understand what you are trying to say with the first part of your post. And even if people were interested in the BO figures for all his films why would that be a problem?
That he alone is not responsible for the success of AC. He's already busted a gut in pre production, filming and seems to be actively involved in post production. And I'm sure actors of high calibre signed up for AC because of Michael's attachment to the project. So I don't understand why there are insinuations he's not pulling his weight or his career will suffer if AC doesn't hit the jackpot at the box office.
If people want to concern themselves over box office figures that's up to them, but I object to them being used to cast aspersions on Michael's superb performances as an actor...which is quite separate from how many bums on seats bother to go and see the films.
