There was this movie, and unfortunately I remember very little about it. I remember seeing it at around 2001-2003ish, so it should be a film that was released before that time. It was definitely in English; at least I think so. Also, it was in colour, if that helps. On the VCR cover, all that I remember is a guys face, and blue background, probably the ocean? The only things that I remember are that there was something to do with water, and by this, I mean like an ocean, or maybe it was something like a submarine or an oil rig, and I think that the main character was a guy, who was either a ghost, or a silvery liquid metally alien/liquidy thing, that looks a bit like the T-1000  in Terminator 2. Sorry for the lack of detail, and please help me remember this!
