NEW YORK -- In an op-ed in the New York Times, Salma Hayek said that her refusals to Harvey Weinstein's advances led to a nightmare experience making the 2002 Frida Kahlo biopic "Frida." 

"For years, he was my monster," Hayek wrote in her account, published Wednesday. 

Hayek, who regularly starred in films released by Weinstein's Miramax in the 1990s, credited Weinstein with helping her start her career. But she said that the movie mogul would turn up at her door "at all hours of the night, hotel after hotel, location after location."

Her refusals -- of massages, showers and sex -- enraged him, she wrote. "I don't think he hated anything more than the word 'no,'" wrote Hayek. 

When Hayek brought "Frida," which she was producing, to Miramax to distribute, Weinstein made outrageous demands as payback, she wrote. Hayek said he insisted on rewrites, more financing and, most heinously to her, a sex scene with full frontal nudity. 

In order to finish what was a labor of love for Hayek, she agreed. But she said she had a nervous breakdown while shooting the scene. "My body wouldn't stop crying and convulsing," wrote Hayek. 

"It was not because I would be naked with another woman," she wrote. "It was because I would be naked with her for Harvey Weinstein."
