all day: Movies

Quentin Tarantino, who hasn’t released a film of his own in nearly four years, made his rep with scripts featuring loquacious felons and their sometimes fatal femmes . Two screenplays he surrendered to other directors in order to get “Reservoir Dogs” made play on a bill at the New Beverly starting Sunday. “Natural Born Killers,” considerably reworked in 1994 by Oliver Stone, follows the satirical adventures of a pair of lovebird serial killers (Woody Harrelson and Juliette Lewis) who become international media celebrities. The story has been turned into an audacious and astonishing vision that comes close to defying description. Ultra-violent, over-the-top and technically brilliant, it’s an emotional barrage. Closer to Tarantino’s original script, though edited chronologically by director Tony Scott, 1993’s “True Romance” features Christian Slater and Patricia Arquette as another pair of lovers-on-the-run, pursued and abetted by a slew of scenery-chewing supporting actors including Dennis Hopper, Gary Oldman, Christopher Walken and Val Kilmer.

* Quentin Tarantino double feature, New Beverly Cinema, 7165 Beverly Blvd., L.A. “Natural Born Killers,” Sunday, 5:10 and 9:45 p.m., Monday and Tuesday, 9:45 p.m. “True Romance,” Sunday, 2:55 and 7:30 p.m., Monday and Tuesday, 7:30 p.m. $3 to $6. (323) 938-4038.
