Released 20 years ago this week (on May 10, 1996), "Bill Paxton.

It was also the "Apocalypse Now" of weather-themed disaster movies. The film's production was marked by severe injuries to the stars and crew, a runaway budget, and the cinematographers openly rebelling against the director. Here are the real-life twists you didn't hear about from the tornado drama's tempestuous shoot.
1. The "Twister" screenplay is credited to "Jeff Nathanson, who was on the set and kept rewriting the script until the end of the shoot.

2. Helen Hunt was director Mad About You," before the end of August 1995. Fortunately, "Mad" producer/co-star Mighty Aphrodite") refused to go brunette.

4. Plagued by sunny weather, the production used bright lamps to reduce the exposure and make the skies look dark and stormy. But the lamps blinded Paxton and Hunt ("These things literally sunburned our eyeballs," Paxton recalled), and they had to wear dark glasses and take eye drops for several days until they recovered.

Paxton and Hunt also took lumps from being pelted with ice chunks in the hailstorm scene. The two leads had to take hepatitis shots after their scene wallowing in a filthy ditch. In that same sequence, Hunt kept banging her head on a low bridge because she would stand up too quickly, and she also was hit in the head by a truck's open enger door in the cornfield sequence. De Bont told Entertainment Weekly, "I love Helen to death, but you know, she can be also a little bit clumsy." Hunt, who blamed her accidents on exhaustion from the difficult shoot, replied, "Clumsy? The guy burned my retinas, but I'm clumsy."5. Tensions flared between de Bont and cinematographer Don Burgess's camera crew. They complained that de Bont would get upset when they couldn't turn on a dime and set up new shots on a moment's notice; he countered that the unpredictable weather meant the shooting schedule had to be flexible. The crew considered getting T-shirts made emblazoned with de Bont's favorite curse-word phrase, "F---ing Hell S---." The breaking point came when a camera assistant walked into the frame and ruined a complicated shot involving noisy wind machines, leading de Bont to shove the man into a mud puddle. Burgess and 20 crew walked. The film was only five weeks into production.

6. De Bont replaced Burgess with veteran cinematographer Jack N. Green. Unfortunately, Green was hospitalized with a back injury when a house rigged to collapse did so while Green was still inside it. With two days left to shoot, de Bont took over camera duties himself.
7. Much of the film was shot in Wakita, Oklahoma, where producers purchased and then leveled eight blocks of existing houses, as well as flattening 30 homes built for the shoot. According to the Twister Museum in Wakita (which contains props and memorabilia from the movie), the filmmakers' destruction of the town was so convincing that a third-party video crew flying overhead saw the fake devastation from the air and landed their helicopter to investigate.

8. With the lengthy and tumultuous shoot, the need for twice as many effects shots as anticipated (because of the uncommonly clear skies), and late re-shoots that added the prologue about Jo's childhood, the budget swelled from $70 million to a reported $92 million. But "Twister" grossed $242 million in North America, becoming the second biggest movie of 1996 (only "Independence Day" earned more). Worldwide, the tornado tale sucked up a total of $494 million.
9. "Twister" was nominated for two Oscars, for Best Visual Effects and Best Sound. It was also nominated for two Razzies, including Worst ing Actress (for Gertz, pictured). The Crichtons won the Razzie for Worst Written Film Grossing Over $100 Million.

10. "Twister" was the first mainstream Hollywood movie released on the then-new home video medium of DVD.
