I had a film on a separate list, on my Iphone, that I was sure i copied from this thread, but a careful scan of the posts here revealed, to my surprise, that no one has recommended it!!
I have no idea how it ended up on my phone memo list, but I watched it and hey - run (don't saunter) out and rent/buy/watch this film if the topic of this thread interests you in the least, (and quite possibly even if it doesn't!):
MR NOBODY
alternate trailer
TAGLINE: "Nothing is real, everything is possible"
About time, alternate realities and the nature of existence/non-existence, there are scenes in it that could be salvia trips, ideas certainly culled from trips to "hyperspace", and a fierce originality overlaid on a complex storyline that still manages to work on an emotional level.
Blew me away. Not perfect, but I don't believe a perfect movie can be made about this topic, so this one is one of the ones that may get as close as one can...
A good chunk of it was shot in Montreal, where I live - I believe the film was a Belgium/Canada/Quebec/UK co-production.
Imagine Benjamin Button on SALVIA!

EDIT: By the director of TOTO LE HEROS (TOTO THE HERO), for those of you who know that excellent film.
