Patrick Frater Asia Bureau Chief Sony Pictures‘ “Madame Web,” a standalone origin story in the studio’s array of “Spider-Man”-based Marvel characters, has been granted a theatrical release in mainland China. The film will open in the country on March 1 — two weeks after the title’s Valentine’s Day bow in North America and multiple international territories, including the Chinese-language markets of Taiwan and Hong Kong. The release marks a welcome opportunity for Sony, which, along with the other traditional studios faced difficulty in securing theatrical runs in China over recent years.
