The Boston Online Film Critics Assn. favored dark-horse indies on Saturday, naming “Snowpiercer” the year’s top film. Tilda Swinton was tapped supporting actress for the film, which the Weinstein Co. released theatrically and on VOD.

Fox Searchlight was a big winner, with its “Birdman” nabbing four prizes: for director Alejandro Gonzalez Inarritu, supporting actor Edward Norton, cinematographer Emmanuel Lubezki, and for acting ensemble. The company’s “Calvary” was a double victor, for actor Brendan Gleeson and for screenplay (John Michael McDonagh).

“Two Days One Night” scored for actress Marion Cotillard and foreign-language film. The film is distributed domestically by Sundance Selects.

The Boston Online Critics clearly favored arthouse fare rather than the major-studio films that are also in the Oscar race. Among the exceptions: the animated film prize went to “The Lego Movie,” and editing to James Hervert and Laura Jennings for “Edge of Tomorrow.” Both are from Warner Bros./Village Roadshow.

Other winners include documentary “Life Itself” and score, Mica Levi, “Under the Skin.”

The group also listed its 10 best: “Snowpiercer,” “Under the Skin,” “Boyhood,” “Only Lovers Left Alive,” “The Babadook,” “Two Days One Night,” “Birdman,” “Calvary,” “Inherent Vice” and “Selma.”
