Ok so a long shot but I remember watching a Tom Cruise film but can’t remember the name of the full story. Helpful, I know! Basically a load of people have to stay in this building that was like a warehouse sort of building. If they left they would be attacked. I can’t remember if it was by aliens or something. Anyway of course Tom Cruise would leave the building with a big gun to go and get supplies..... anyone know what it is called??
