It’s an advertising trick of practically evil subtletly, but the five-film series “The Hire” is still worth a look. Ostensibly a collection of short films directed by some major talent — John Frankenheimer, Ang Lee and Guy Ritchie among them — and all starring the highly cool Clive Owens from last year’s “Croupier,” these films are, at heart, a disturbingly clever campaign for BMW cars. The film releases are staggered, with Frankenheimer’s “The Ambush” available for viewing right now, and Ang Lee’s “Chosen” due next week. The one I’m really waiting for is Wong Kar-Wai’s “The Follow.”
