Are you referring to “In Time”, or some other film? The Man From Earth is another interesting film about a singular immortal man.
There is heaps to unpack, it really is a complete game changer.
The other issue, is what about other animals. If they end up immortal as well, we’d be litterally drowning in any animals that breed rapidly, like rats, rabbits etc.
In time only solved ageing, everyone was still mortal, so you could still die from a car crash or being shot. And there definitely was a tiered classes system in place, with the rich having more “life”, and the poor literally living paycheck to paycheck.
I really liked it, should watch it again.
