Sideshow: Melissa Rivers files suit in mother Joan's death

Joan Rivers' daughter, Melissa, filed a multimillion-dollar lawsuit Monday against the clinic where her mother underwent a throat procedure that went horribly wrong and led to her death on Sept. 4. Melissa, 47, a University of Pennsylvania alum who costarred with her mother on several E! series, claims that Yorkville Endoscopy in Manhattan and its staff are guilty of gross medical malpractice because they did not do enough to restore Joan's breathing by performing a tracheotomy. Rivers, 81, suffered brain damage due to oxygen deprivation.

"The level of medical mismanagement, incompetency, disrespect and outrageous behavior is shocking," says Melissa, whose suit also names her mother's personal doctor, Gwen Korovin. "Not only did my mother deserve better, every patient deserves better."

The clinic has yet to release a statement.

Tom Cruise is so excited for you to see his latest sequel, Mission Impossible 5, that the release date has been moved forward by five months to July 31. . . . Emile Hirsch, 29, who was at Sundance for the premiere of his new film, Ten Thousand Saints, is in a pickle. Police in Park City, Utah, are investigating a criminal complaint filed by a Paramount executive who says Hirsch assaulted her Sunday during an argument. . . . Filmmaker Ava DuVernay and thesp David Oyelowo, who are expected to clean up at the Oscars for their civil-rights-era film Selma, are teaming up to make a drama about Hurricane Katrina. It'll be a love story and a murder mystery with loads of water, says Variety. . . . Harry Potter's Emma Watson, 24, said Monday that she's been cast as Belle in Disney's live-action version of Beauty and the Beast. Watson writes on Facebook that Disney's 1991 animated version "was such a big part of my growing up, it almost feels surreal that I'll get to dance to 'Be Our Guest' and sing 'Something There.' "
