I was trying to figure out why I didn't remember most of this, finally went and checked the synopses and realised that is because I watched RED2, not RED. But fair comments I think. Possibly creepiest for this (and worse for being supposedly a romantic comedy) is Overboard where Kurt Russell convinces an amnesiac Goldie Hawn she's his wife and she lives the role for several months. It's a long time since I've seen it, so I don't recall how they handle the specifics, but euuuwww...
