In his first starring film role (and one played on Broadway by Douglas Fairbanks), Buster Keaton is "The Saphead," ne'er-do-well son of a Wall Street tycoon who manages to save his father from bankruptcy. Plus, Keaton's first solo short subject, "The 'High Sign'" (1920), finds him helping a town that's been taken over by a "secret society," while newlywed Buster's plans to build a pre-fabricated house in "One Week" (1920), hilariously amok when a jealous ex-suitor rearranges the pieces. 115 min. Standard; Soundtrack: mono musical score. Silent with music score.
