Does that film considered as a 2014 film or 2015?

Normally year of origin seems to be based on cinema release. The Hurt Locker won for Best Picture 2009 because it was released properly, despite doing the festival circuit in 2008. So it is 2014 as it was released in some territories

What difference does it make?





Schrodinger's cat walks into a bar, and / or doesn't.
