Warner Bros. is developing an untitled drama that will examine the relationship between “Cosmos” author Carl Sagan and his wife and collaborator Ann Druyan, TheWrap has learned.

Lynda Obst, who produced the space exploration movies “Interstellar” and “Contact,” will produce with Druyan.

Sagan is the famed astrophysicist who wrote the novel that served as the basis of Robert Zemeckis’ “Contact,” which was executive produced by Druyan.

Zach Dean (“Deadfall”) will write the script, having previously written “Methuselah” for Warner Bros. and “Harry Potter” producer David Heyman.

The Sagan-Druyan project comes on the heels of “Theory of Everything,” Universal’s drama about Stephen Hawking and his wife Jane Hawking that was nominated for five Oscars, winning one and grossing $121 million worldwide on a $15 million production budget.

Druyan is an author and Emmy-winning writer of the recent series “Cosmos: A Spacetime Odyssey,” which she also produced. She married Sagan in 1981.
