Steven Spielberg reveals how 'Star Wars' creator George Lucas helped him make 'Jurassic Park' and 'Schindler's List' in the same year

• Steven Spielberg said he asked George Lucas to help him make "Jurassic Park" and "Schindler's List."
• The director was so impressed with the "Schindler's List" script he wanted to film it straightaway.
• The "Star Wars" creator then helped Spielberg finish the sound editing on "Jurassic Park."

Steven Spielberg has directed some of the most beloved movies of all time, including several critically acclaimed films during the 1990s like "Jurassic Park," Schindler's List," and "Saving Private Ryan."

But some audiences might remember that "Jurassic Park" and "Schindler's List" both came out in 1993, and Spielberg had to call on some extra help to ensure they both arrived on time. 

"The Late Show with Stephen Colbert" recently released a bonus clip from the host's interview with the director, in which Spielberg explained that he had been developing "Schindler's List" for 10 years "to work up the nerve" to make it, because "it was such a responsibility in telling that story."

Spielberg explained that he'd only just finished shooting "Jurassic Park" when he first read Steven Zaillian's script for "Schindler's List," which meant he still had plenty of work to do in post-production on the dinosaur adventure.

The director explained that he read the script with his wife, Kate Capshaw, and he knew by "page 167" that he had to make the movie as soon as possible because he didn't want to miss wintertime in Poland and have to wait another year to start work on it. 

Spielberg said he immediately called his producer, the current Lucasfilm president Kathleen Kennedy, to tell her that he needed to jump from "Jurassic Park" to "Schindler's List," even though there was still "[sound] mixing, color correction, and sound effects" left to finish on the movie.

Thankfully Spielberg was able to call on "Star Wars" creator George Lucas to supervise the remaining sound work on "Jurassic Park."

He explained: "I asked George Lucas if he would supervise the dub. And George came in and dubbed the picture for me."

Spielberg referred to Lucas as "a best friend, always."

"Jurassic Park" would go on to win best sound effects editing and best sound at the 66th Academy Awards in 1994, which wouldn't have been possible without the "Star Wars" creator's involvement.
