SIN NOMBRE 
(Comcast Movies and Events) Cary Fukunaga’s debut follows a Mexican gangster (Edgar Flores) and a Honduran woman (Paulina Gaitan) trekking north to the United States atop a freight train. He’s on the run. Soon, so is she. Despite the film’s being well meant and better made, you can always see strings yanking. (R; runs through Oct. 29) WESLEY MORRIS
NIGHT SHIFT 
(Encore on Comcast) Ron Howard’s deft offbeat comedy introduces a new talent. His name is Michael Keaton and he plays a motormouthed punk who works with Henry Winkler in a city morgue. Keaton keeps things moving until the comedy dissolves in bathos. (R; runs through Oct. 29)
