I decided, was it was a side effect of traveling faster than light to reach earth. He warped in and put of the timeline momentarlit. I'd say he was psychic but the people from the past seemed to see him as well. It could still be esp but FTL TRAVEL side effecr suits me more. Hope u like my idea!
shareI don't think that's it. But I wonder too. I got the impression he can see past and future, thus how he makes a fortune (stock market) and gets 9 basic patents so quickly. I wish they elaborated more on this in the beginning. He has flashbacks to the past for sure, but also seems to see a few in the future at the lake (he sees the house before it's built). It's also possible he's immortal and is just remembering the distant past or past lives or seeing someone else's visions of the past. He doesn't age in the movie, but everyone else around him does.
At at least two times, Newton says he thought of Bryce just before/night before he saw him. Once Bryce thinks he sees Newton behind him at the dock. The other time is the ending when he shows up at the bar. He also witnesses Bryce in his head during the sex scenes. This implies Telepathy.
Still working on figuring everything out. Just saw it this week.
He's from Mars in the book but the film is ambiguous.
The explanation is that he is psychic.
