April 27 (UPI) -- Oscar-winning filmmaker Steven Spielberg said his old friend Robin Williams helped him wind down after grueling days of shooting his 1993 Holocaust drama Schindler's List in Poland.
The 71-year-old director talked about the experience Thursday night at a Tribeca Film Festival screening of the movie, which was followed by a panel discussion that included cast members Liam Neeson, Ben Kingsley, Caroline Goodall and Embeth Davidtz.
