We’re watching Darren Aronofsky’s The Foutain which takes place in three different time periods (ca. 1500, ca. 2000, and sometime far in the future), and which made the dubious choice of showing the 1500 era timeline out of sequence.
But I was reminded of the 1944 Michael Curtiz film Passage To Marseille with Humphrey Bogart as a (heh) Frenchman. (We viewed the French differently back then.) Passage to Marseille is told in a flashback. Then that leads to a flashback. Which itself leads to a flashback.
At one point, if I’m not mistaken, you’re five flashbacks deep.
I can’t remember now if all the flashbacks are even reliable.
The Fountain is freaky.
