Yeah, not much on that list interests me. Perhaps Hangar 18, Ticks, and maybe a couple others. Good thing Lionsgate already put out Cujo and The Monster Squad on BD, no need to worry about those ones.
And in regards to The Keep: I think if Olive had access to that one, they would've already released it. For whatever reason (maybe Michael Mann?), Paramount seems content to leave that particular title buried forever.
