The Machinist

(Showtime on Comcast) Christian Bale dropped 60 pounds for his role as a paranoid machine-shop worker who hasn’t slept in more than a year, a feat that goes beyond De Niro-esque transformation into the valley of masochism. Someone tells the character, “If you were any thinner, you wouldn’t exist” and sadly, that’s also true of Brad Anderson’s movie, a stylish but shallow puzzler that plays like a “Twilight Zone” episode filmed on the sets of “Seven.” (R; runs through April 1)

Ty Burr

The Last Station ½

(Starz on Comcast) An entertainingly unrestrained melodrama about the last days of Leo Tolstoy (Christopher Plummer), when his utopian admirers are battling his wife for his soul and the copyright to ‘‘War and Peace.’’ Helen Mirren plays the Countess Tolstoy as a grandly spoiled diva moved by genuine love; it’s a brilliant feat of overacting. With James McAvoy and Paul Giamatti. (R; runs through April 4)

Ty Burr

Bully ½

(Showtime on Comcast) Like his auspicious debut film, 1995’s “Kids,” Larry Clark’s 2001 film is as lurid and gripping as a tabloid headline, difficult to look away from. But “Bully,” about a group of teenagers in suburban Florida who plan and carry out the murder of a despicable guy in their circle, is even more voyeuristic than “Kids.” With its gratuitous crotch shots and abundant images of young, hard, naked bodies routinely engaged in (often kinky) sexual activity, “Bully” veers disturbingly into exploitation. (Unrated; runs through April 1)
