Entertainment Movies Robin Williams Did 'Stand-Up Over the Phone' to Lift Steven Spielberg During 'Schindler's List' The director said the phone calls were the highlight of his week By Jodi Guglielmi Jodi Guglielmi Instagram Twitter Writer-Reporter, PEOPLE People Editorial Guidelines Published on April 27, 2018 11:54 AM Share Tweet Pin Email Steven Spielberg had a famous friend to lean on during the making of Schindler’s List. During a 25th anniversary celebration of the Oscar-winning film at the Tribeca Film Festival, Spielberg said he relied on weekly phone calls from Robin Williams to keep his spirits up. “Robin knew what I was going through, and once a week, Robin would call me on schedule and he would do 15 minutes of stand-up on the phone,” Spielberg said on Thursday, according to IndieWire. “I would laugh hysterically because I had to release so much.” Spielberg and the late actor had worked together a few years prior on the 1991 film Hook. Schindler’s List told the story of a German businessman who helped save the lives of thousands of Polish-Jewish people during the Holocaust.

The subject matter and the impact the film had on all of us … took sort of the celebration out of that.” Williams passed away at the age of 63 in 2014 after suffering from Lewy Body Disease, a type of dementia that effected his thinking, memory and movement control.
