I bet this was discussed in the 120 post thread but please humor me....
Since Leanard has full memory before the accident he would know that his wife was or wasn't a diabetic right? So when Teddy tells Leonard that his wife was a diabetic, not Sammy's wife Leonard should know. Correct?
I just saw the movie a week ago and thought that movie was the best I have seen in awile.
I loved how the movie was filmed backwards, like Greg stated it puts us in Leonard's shoes by not knowing what happened earlier.
