~Speaking of Seth~

This was a delightful movie on many levels. It touches the concepts of choosing our parents before birth, our  amnesia, free will, probable selves,  physics theories (multiverse, nonlinear time, expansion/contraction of the universe, chaos, string, changing the past), questions sequential time, includes the butterfly effect, all wrapped up in good acting, great cinematography, some fantastic and clever dreamlike scenes, with a great music track to boot. There is so much to it, so many twists and turns, that it held my complete attention through the entire 2.5 hours. It's on Netflix, I definitely will watch it again to see what clever things I missed. I have to say it is the cleverest movie I think I've ever seen.

"Nemo Nobody, a 118-year-old man who is the last mortal on Earth after the human race has achieved quasi-immortality. Nemo, memory fading, refers to his three main loves and to his parents' divorce and subsequent hardships endured at three critical junctions in his life: at age nine, fifteen, and thirty-four. Alternate life paths branching out from each of those critical junctions are examined. The speculative narrative often changes course with the flick of a different possible decision at each of those ages. The film uses nonlinear narrative and the multiverse hypothesis style."

Here's the Wiki, but don't spoil the movie for yourself if you plan to watch it.
