What's happening today in pop culture:

• The premiere of a movie about the Electric Daisy Carnival techno-music festival brought out thousands of uninvited guests — and the LAPD's riot squad — to Hollywood's Grauman's Chinese Theatre. And Twitter is apparently to blame. [Los Angeles Times, Hollywood Reporter]

• Polly Platt — the production designer on "Terms of Endearment," the writer of "Pretty Baby," a producer on "Say Anything," "The Last Picture Show," "Paper Moon" and "What's Up, Doc?," and the inspiration (thanks to her divorce from director Peter Bogdanovich) for "Irreconcilable Differences" — has died at 72, after a long battle with ALS. [The Wrap]

• The George Clooney-directed "The Ides of March" will open the Venice Film Festival on August 31. Also on the slate: Roman Polanski's "Carnage," Steven Soderbergh's "Contagion" and Andrea Arnold's "Wuthering Heights." [Hollywood Reporter]
