I was at the cinema the other day, and as I was walking in (after I'd got my ticket - for Valentine's Day - and was on my way to the screen) I passed an employee in the lobby, who didn't seem too busy (she was pretty much just standing there). On a whim, I turned to her and asked "Excuse me, but is Micmacs in English or French?"
"The film, Micmacs. Do you know if it's in English or French? I've never seen any indication that it's not in English, but none of that directors other films were, so-"
"Never heard of it."
Then she walked off. The film's been out since the 26th.of February, and while it's not the latest hollywood blockbuster, it's not exactly an indie film with no advertising or exposure. Since she works there, I don't think it was too unreasonable to expect her to have heard of it.
If anyone cares, I asked someone else upstairs, and Micmacs is in French, with English subs.
