I t’s likely that most audiences going into the surprise documentary smash You Can See Everything are familiar with either its nominal subject (and literal poster gal with an intense stare) Elizabeth Holmes, the tech founder serving a prison sentence for defrauding investors; or the film’s on-camera co-director Nathan Fielder. Holmes, as the movie points out, was all over the media as her company Theranos was hyped to the moon and then spectacularly imploded; she was also played by Amanda Seyfried in the well-regarded Hulu miniseries The Dropout. Fielder, meanwhile, may not have graced as many magazine covers, but is similarly familiar to prestige-TV acolytes from his comedy-reality series Nathan for You and its successor, the more reality-bending series The Rehearsal. A third figure not included in the film’s ad campaign becomes a key part of the film in the second half, and will also be familiar to many viewers.

This should leave Billy Evans as the odd man out.…
