The VFX supervisor went to a Beverly Hills hospital around noon Sunday after experiencing intense pain all day. Cleared of appendicitis and kidney stones and given painkillers by the doctors, Saindon decided to attend the Oscars, but went back to the hospital in pain after his pressroom interview.
On the second hospital visit, doctors found the ruptured small intestine and operated to fix it, IndieWire said.
Sunday's trophy was the first Oscar for Saindon, an American visual effects supervisor who lives in New Zealand. He and his cohorts were also honored this year with a BAFTA for their "Avatar: The Way of Water" work. Saindon was nominated for Oscars for "The Hobbit: An Unexpected Journey" in 2013 and "The Hobbit: The Desolation of Smaug" in 2014.
Saindon's resume includes VFX supervisor gigs on the "X-Men: The Last Stand," "Night at the Museum," the first "Avatar" and "The Hobbit" films, and he was a senior VFX supervisor on "Avatar: The Way of Water." He has worked at Weta since 1999.
