A pair of Japanese tourists — a brother (Rintaro Sawamoto) and sister (Atsuko Okatsuka) — are temporarily stranded in a Southern California desert town in Mike Ott’s rambling, mildly engaging micro-budgeted indie.

Staying at a motel while awaiting a replacement for their rental car, Sawamoto, who speaks a few words of English, makes friends at a party next door. Okatsuka, who doesn’t understand English at all, is romantically pursued by a would-be male model (Cory Zacharia) but is interested in another guy (Brett L. Tinnes).

A mumblecore-ish slice of life, “Littlerock” is a fairly shapeless odyssey, at least until the siblings finally arrive at their destination — the museum at the former internment camp at Manzanar, where Japanese-Americans were imprisoned at the outbreak of World War II.
