It’s in color, probably from the early 2000’s.  It’s in English and I saw it on TV. It takes pace at a military base that is mostly underground. The soldiers wear white T-shirts. They have an invisible creature inside a kind of electronic cage. The only woman present is (I think) a reporter, A man with white hair arrives and disapproves of the project. The invisible creature escapes and makes somebody dance and then kills he white haired man by making parts of his body disappear. It then escapes outside and bounces a ball along the ground as it leaves. The woman also escapes outside but is captured by the base commander and put inside the electronic cage. He then kills her and what I guess is her soul rises from her body but cannot leave the enclosure.
