Woody Harrelson stars as morally-lax LA cop Dave Brown in this nihilistic take on the so-called Rampart police corruption scandal of the late 1990s. It's co-scripted by James Ellroy and includes a raft of star turns (Sigourney Weaver, Ned Beatty, Steve Buscemi, Robin Wright and Anne Heche among them). It's Harrelson's performance as the fascistic Brown that commands the attention, though. Not an easy watch (or listen: I had the subtitles on at points), but a powerful movie that has had an undeservedly limited theatrical release.

Once Upon A Time In Anatolia (15)

Turkish director Nuri Bilge Ceylan's film won the Grand Prix at Cannes last year and is a crime drama of sorts – at least in the sense that it follows three carloads of policemen, gravediggers and suspects as they drive round the Turkish province of the title looking for a buried body which is central to their murder investigation. CSI Ankara it ain't: slow-moving, panoramic and thought-provoking it certainly is.

21 Jump Street (15)

Taking the late-1980s American TV series of the same name as its starting point, Phil Lord and Chris Miller's film stars Channing Tatum and Jonah Hill as cops whose youthful appearance makes them perfect for tackling crime in high schools. Johnny Depp, who first found fame in the original series, adds to the satirical undertow by reprising his role (if only briefly).

The Lorax (U)

A new 3D version of Dr Seuss's environmentally-themed story screened at the Edinburgh International Film Festival last month and hits UK cinemas on July 27. In the meantime, feast on this animated 1972 TV adaptation made for US network CBS. It was directed by Hawley Pratt, the man behind Speedy Gonzales and a longtime collaborator of animation great Friz "Looney Tunes" Freleng, and features the voice of actor Eddie Albert, a noted environmental activist in his own right.
