“X-Files” vet R.W. Goodwin revisits that Fox TV show’s longtime base of Vancouver to revisit fifties sci-fi filmdom. The outcome is a simple-minded spoof made with a little verve. Writers Steven Fisher and James Swift open with a cute setup about a long lost unreleased 1957 sci-fi film titled “Alien Trespass.” This black-and-white newsreel reporting that mogul “Lewis Q. Goldstone” burned the negative in a contract dispute segues to “Our Feature Presentation” in color. A spaceship crashes, an alien entity commandeers a handsome scientist, live human breasts are deformed by conical bras, pie and coffee are served at the diner, law enforcers harass juvenile delinquents, townsfolk turn into brown viscous puddles, and locals watching “The Blob” flee the local theater when the alien attacks, just like the audience in that 1958 film when that monster attacked that theater. For better fun with the genre, check out “The Lost Skeleton of Cadavra” from 2001, or the TV ads for Hulu, an Internet conduit for TV hyped as “An evil plot to destroy the world. Enjoy.” With Eric McCormack, Jenni Baird, Dan Lauria, Robert Patrick, Jody Thompson, Aaron Brooks, Sarah Smyth, Andrew Dunbar, Tom McBeath, Vincent Gale, Jerry Wasserman. 88m. (Bill Stamets)
