The 11th Green begins understated: A passive reaction to a fantastical sighting; a monotone news report about preposterous technology. But audience beware: like a frog in a pot of slowly heated water, you won't know what hit you until you are boiling alive in the multi-faceted, technicolor time warp of auteur Christopher Munch's making. It's beautifully shot - some great desert frames and lasting images stick out as calming amongst the intellectual chaos. The briefly seen low budget CGI doesn't take away from the story - there's no time to unsuspend your disbelief when you're wrapping your head around outlandish hypotheticals intertwined with true to life historical figures, places, and events. The performances are acutely fun for the historically attuned. A psychedelic fever dream for the US history buff - or an active rejection of recent human history as we know it - you decide. This movie is the definition of what Sundance used to be for.
