Universal/Getty "I think I just lost it." Phrases like that are repeated bySteven Spielbergin the newNational GeographicdocumentaryJaws @ 50: The Definitive Inside Story. The great director, who pole-vaulted from "promising newcomer" to "visionary behind the biggest moneymaker of all time" with the shark-hunting adventure, is clearly still rattled by the psychological torment of leading the massive, costly, and difficult production at the age of 26. It's been long known thatJawswent substantially over budget and went 100 days beyond its original schedule. (Indeed, there has beena Broadway playabout this!) But to see the grandfatherly Spielberg, whose work feels infallible today, reflect on it so long after the fact is one of the more striking elements of this extremely watchable documentary. Diltz/Rue Des Archives/Everett The problems were many. The studio rushed the film into production, hoping to capitalize on the tremendous book sales. (Spielberg admits, however, this may have been a boon in some respects. The mechanical sharks weren't ready to shoot the prologue, and this made him realize it may be scarier, in fact, tonotsee the threat until later in the movie.) The three enormous fiberglass sharks were technical marvels, but designed for freshwater. No one thought about the implications of shooting in seawater and the negative effects of electrolysis. This made for an endless series of delays, which afforded starsRobert ShawandRichard Dreyfussto get on one another's nerves. (This may have ultimately helped their performances, but made for stress on set.) Shaw was also a heavy drinker, so occasionally there'd be times whenfinallyeverything would be working, but he couldn't nail his dialogue. Then came the headaches of shooting on water in general. (One time, the boat took on too much water and sank.) AsJames Cameron, who knows a thing or two about making wet movies, said in the documentary about filming on water, "It doesn't get twice as hard — it instantly gets five times as hard."

Jawswas Spielberg's first big studio opportunity after working in television and making one small feature,The Sugarland Express. With so much money at stake, Hollywood trades were already speculating if he'd ever work again once he got back from the Martha's Vineyard location. His advocate at Universal,Sid Sheinberg, even flew across the country to sit him down and say, "This can't continue." The frustrations of the actors, crew, and studio investors were on Spielberg's shoulders, but he stuck to his guns because he knew what the movie could be if he got the shots that he needed. (He did, as reported in the doc, regularly call his mother and freak out. "Mommy, this is really impossible. Help!" he quoted himself as saying.) "When the film wrapped Martha's Vineyard, I had a full-blown panic attack," he said. "I couldn't breathe, I thought I was having a heart attack. I couldn't get a full breath of air. I kept going to the bathroom and splashing water on my face. I was shaking." Courtesy Everett He continued, "It was everything that I had experienced on the island, trying to hold myself together, but hold the crew together. I felt really responsible for keeping them there for as long as we had to stay." Even thoughJawswas a box office hit and cultural phenomenon in excess of anyone's dream — making the cover of bothTimeandMADmagazines — and it set Spielberg on a career path that ensured he'd always have final cut (and could even co-create his own studio years later), "it didn't stop the nightmares." Spielberg confessed, "I had a real tough time when I finished the movie." He described waking up regularly in a cold sweat, with "the sheets soaking wet. We didn't have the words 'PTSD' in those days, and I had consistent nightmares about directingJawsfor years afterwards. I was still on the movie, and the film was never ending." Spielberg later described how, for years, he would sneak onto theJawsboat, Orca, after it was moved to theUniversal backlot tour. There, as if returning to the scene of a crime, he would crouch down out of view, and sob. "I had nothing to cry about," he said. "The film was a phenomenon, and I'm sitting here shedding tears because I'm not able to divest myself of the experience. The boat helped me to begin to forget. That Orca was my therapeutic companion for several years afterJawscame out." Jaws @ 50: The Definitive Inside Storyisn't just about the director's trauma, however. It shares several behind-the-scenes tales and commentaries. (If you want to watch directorSteven Soderberghspeak with such reverence about the camera placement and editing inJawsthat it looks like he's about to cry, you really must watch it.) Check out the trailer below. Jaws @ 50: The Definitive Inside Story premieres July 10 at 9/8c on National Geographic and streams the next day on Disney+ and Hulu.
