@tsarstepan,
Fair enough, it's not normally the case that something is released over here first, not at the cinema anyway.
On Pointless the other day the category was phrases involving food. The story that goes with 'spill the beans' was that it comes from the ancient Greeks who would vote using a black or white bean. If someone knocked over the container and spilled the beans the result would be known early.
Having said that they thought it was apocryphal.
