Man broadcasting on the radio after an apocalypse

I only have an extremely vague memory

All I really recall is a man broadcasting on radio equipment after some form of apocalypse, it was live action and I believe made within the last decade

Something had happened to most of the population I think it was some kind of alien hive mind taking them over or something in that general vein

EDIT: It was in English and I watched it within the last few years fairly certain its a relatively recent movie (within the decade at least) and it was in color. I really do not have much detail its really only the vaguest of memories
