At 1:22:30, the protagonist, Toby, utters this line. So I did stop the film, made a sandwich and cup of tea, then decided to watch to the end, which didn't come soon enough.
As visual art, the film is superb. But as a story, it is confusing. With all its bizarre references self-reflexivity, the central story becomes a side plot.
It was visually beautiful, well-acted, great costumes and music, but thoroughly disjointed and confusing for much of the time. It had me thinking "this movie wasn't made for an audience".
