When Christopher Nolan was doing research for "Oppenheimer," he quietly joined a walking tour of the grounds in Los Alamos, N.M., the epicenter of the Manhattan Project.
The director was so impressed that he decided to turn this tucked-away town of 13,000 into a Hollywood lot. For two weeks in spring 2022, celebrities including Matt Damon and Emily Blunt shot in local locations, including the former cottage of J. Robert Oppenheimer, the key figure in America's quest to build an atomic bomb and win a war.
That house probably won't be open to the public until later this year. But Los Alamos is already worth exploring.
In June, I started with the free Bradbury Science Museum, named after Norris E. Bradbury, who replaced Oppenheimer as head of the Los Alamos National Laboratory. Fortunately, the gregarious security guard didn't evict me for assuming the center would be a tribute to science fiction writer Ray Bradbury.
The exhibits detailing the lab's work on stuff like algae biofuels and nanotechnology went over my head. But the film "Racing Toward Dawn," which chronicled how Oppenheimer and his colleagues picked this city for its secret experiments, was geared toward dimwits like me.
It was the perfect prep for the $25 deluxe walking tour that embarked from the Los Alamos History Museum gift shop, just three blocks away.
Before my group of seven took off, I had time to check out a few displays. My favorite nugget: a copy of the daily "secret" newsletter from Dec. 22, 1943, which warned readers to recycle their Coca-Cola bottles and to avoid burning their Christmas trees. It also let folks know that the featured movie that evening would be "Old Acquaintance" starring Bette Davis.

History tour
Our tour guide, Kathy, preferred to serve up history in chronological order, which meant our 90-minute walk started with a stop at an 800-year-old ancestral Pueblo site. She soon jumped centuries ahead to the period in which Los Alamos played host to the all-boys Ranch School, whose students included future Sears, Roebuck president Arthur Wood and writer Gore Vidal.
