“When I see a PlayStation, when I look at a cell phone — from the smallest calculator to an iPad — I look at my dad and I say, ‘My dad and a team of geniuses started that,’” Steven Spielberg, 73, said of his father, according to Variety.
Steven Spielberg and his three sisters, Anne, Nancy and Sue said in a statement that their father taught them to “love to research, expand their mind, keep their feet on the ground, but reach for the stars [and] look up,” according to the Reporter.
The director said his father also helped him with the first film he ever made when he was 17 called “Firelight,” which showed in one movie theater in 1964 and he has said his father’s experiences in the war inspired him to direct “Saving Private Ryan.”
In 2012, he was awarded the USC Shoah Foundation Institute’s inaugural Inspiration Award for his work in creating a system to record the testimonies of thousands of Holocaust survivors. The Shoah Foundation was founded by Steven Spielberg.
