Amnesia related films

I looked at films that Amnesia themes in it, so I did some research and came across a film called Long  Kiss Goodnight which is about a mother and teacher in Pennsylvania who was found, washed up on a New Jersey beach, pregnant, injured, and suffering from complete amnesia. The film itself has been given an action film genre but a sub genre of amnesia which is why this film is good for us to look at because it gives us a clear idea on what to include in our final film opening, also it gives us a better understanding on Amnesia itself.
Long Kiss Goodnight

I watched the trailer to see what the film was about, the mother is suffering from a bad case of amnesia and can't even do simple things like cut food up, but then it takes a sudden change and she starts to remember and she becomes overwhelmed that she can remember, she remember that she was an assassin which is where the film takes you; into an action packed scenario. 
Spellbound
I looked at another film called Spellbound which is about a man who suffers from severe amnesia and runs off to New York trying to get the bottom of his true identity. Spellbound tackles the theme amnesia but also it is widely considered the first mainstream film to truly tackle to subject of psychoanalysis  I tried looking for the trailer but unfortunately it had been terminated due to multiple third party notifications of copyright infringement.

Finding Nemo
I came across a film that i wouldn't assume would be associated with Amnesia, Finding Nemo is known as an animated children's film. The amnesia aspect is shown in the character Dory, she is a fish that suffers from short term memory loss. This is used for comedic effect but it is a clever way of dealing with such a serious issue in a children films

This scene shows Dorys short term memory loss in an amusing way, it shows that nemos father is confused in why Dory doesn't remember showing him the way to the boat, but the Dory explains that she has short term memory loss. This is a good film to look at as it gives us an understanding on short term memory loss whereas the other films show servere amnesia.
