A question about the memory/ simulation
I thought this was a brilliant film - the execution was good, the characters compelling and the unraveling of the truth perfectly timed.
I have a question that keeps nagging, and I could not find the answer for it on these boards (I might have missed it). The story requires for the viewer to suspend disbelief; fine, I have no problem doing just that. But one thing doesn't add up, even when I accept everything happening in this film as a possibility. Namely; how was the main character able to freely move around the train?
According to the story, the last 8 minutes were retained on the brain of the deceased teacher. And Gyllenhaal's character could access those final eight minutes again and again.
Would this not limit him to just the conversation he was having with his companion? He would not have been able to see what was going on behind him, much less in other cars of the train, at the station or inside the van. He could not have known about the wallet being thrown back inside the train.
But he does just that; getting up, going into the lavatory, opening the ceiling and finding the bomb. Then going into the station, down into the men's room.
If this is all a simulation it could work of course; the simulation adjusts according to where he needs to go.
But the character is looking for the bomber. And for that he needs to be able to open bags from fellow passengers - the contents unknown to him. He has to access the conductor's space; without knowing what it looks inside. And he has to find the bomber - without having a clue of what this bomber looks like (even gender is an uncertainty.)
If we are to consider the teacher only spoke to the woman across from him, he would not have access to this wealth of information.
The only way I could explain it; all memories of all passengers were stored (doubtful, considering the blast), and through this he has access to every part of the train, the station and the car park (and the van containing the dirty bomb).
Is there another explanation? Have I missed a vital clue? Thank you for any insight!
