Gadot is also producing the film with her newly formed Pilot Wave with producing partner and husband Jaron Varsano. The Warner Bros. project is also being produced by Marc Platt, reports variety.com.
Justine Juel Gillmer, whose credits include "Harry Haft", will be writing the screenplay, based on Sendler's work in the Polish underground in the Warsaw Ghetto during World War II.
Sendler worked with dozens of others to smuggle out children, provide them with false identification and place them with families. She was arrested by the Gestapo in 1943 and tortured but never revealed any information about the children.
Gadot, a native of Israel, is also producing and starring in "Wonder Woman 1984", which will open on June 5. She is also starring in Kenneth Branagh's "Death on the Nile" as Linnet Ridgeway-Doyle in a sequel to "Murder on the Orient Express". She also has a project with Dwayne Johnson and Ryan Reynolds in Netflix's "Red Notice".
