On adverts recently it's being said like 'Wally'. I used to think it was meant to be a take on that word but it didn't sound right because it's spelt Wall instead of Wal. Is it just cos in America Wall is pronounced like they are saying Wal cos of the accent? The name confusion has totally put me off the film already...

PS why are there no trailers on TV for it? I have no idea what it's about.
