Forget, if you can, the iconic ending of the original Planet of the Apes, and consider the rest of the movie. The 1968 film was based on Pierre Boulle's original novel, with a script by Rod Serling that was rewritten by Michael Wilson. It was expensive, it was risky (what major studio was doing serious science fiction in the late '60s?) and it became a massive hit. Everything from Charlton Heston's unforgettable performance, John Chambers' revolutionary makeup effects and the tense, sinewy Jerry Goldsmith score came together in perfect synchronicity. It's an American masterpiece, which is why Turner Classic Movies is celebrating the film with a pair of showings in movies theaters across the country. You can see Planet of the Apes locally at 2 and 7 p.m. today at the Weherenberg Des Peres 14 Cine (12701 Manchester Road, Des Peres; www.fathomevents.com). TCM host Ben Mankiewicz discusses the background of the film and its making as part of the screening. Tickets are $12.50.
