The "Hollywood amnesia", where you forget who you are, is technically called retrograde amnesia, where you forget the past. The "forget who you are" stuff is a very extreme case, but in a milder form, it's actually common with head injuries. It results in the person not remembering the incident in which they receive the head injury, and sometimes hours to days before.
The "Memento" type amnesia is called anterograde amnesia, and I believe it is very rare. That's where you can remember stuff before the injury, but you can't form memories afterwords. It comes from injury to the part of the brain that processes memories, either the hippocampus or the amydala, I forget which. (Pun NOT intended.)
