The moment he 'turns' into him is the moment he reads the scrapbook after he shoots him. Right after the screen goes to black.
@MajorMercyFlush Yeah, I figured that. But it seemed like they were setting up a moment he goes crazy. They mention you can't travel more than 53 years before or after the zero point and that too much time travel makes you crazy. But this never really comes into play.
It seems like there was a cut scene where Ethan Hawke decides he has no choice but to travel 54 years and then goes crazy and then fizzle bombs some people.
I get why they ended it where they did, to focus on the "mind-blowing" everyone is the same person reveal.

A really great movie. Time Travel stuff is at its best when it tells personal stories like this one. It is also best when everything spins out of control and the timeline is just a mess afterwards.
This movie makes me proud of Australian cinema.
Minor Spoilers:
The ending is a bit of a dud moment. I don't think the reveal was as dramatic as they intended. I would have liked to see the moment Ethan Hawke turned into Old Ethan Hawke and the movie seemed to be setting that up, but just never showed it.
