“Lisa Picard is Famous”

A t the end of “Lisa Picard Is Famous,” Griffin Dunne says, “Sometimes reality just needs a little push.” Apparently, that’s what the filmmakers were trying to accomplish with this mockumentary. Dunne portrays a filmmaker named Andrew, whose goal is to document a person on the brink of fame. But fame is a nebulous thing, and trying to anticipate who will become famous enough to sell his documentary is a crapshoot. He thinks he has found a winning subject in Lisa Picard, a Penelope Miller look-alike who has won some notoriety for starring in a suggestive cereal commercial.
