Under the three-year deal, the comic book great behind such titles as 'Y: The Last Man' and 'Saga' will bring his creator-owned comics and new titles to the big and small screens.

Comic book legend Brian K. Vaughan is expanding his media empire.

Vaughan, the creator of the critical and commercial hits Y: The Last Man and Saga, has signed a three-year overall deal with Legendary Entertainment to adapt his work and create new titles for film and television. Sources say the agreement is in the eight-figure range and represents the largest overall film and TV pact to date for a comic book creator. The deal arrives as FX is expected to hand out a series order to Vaughan's adaptation (with Michael Green) of Y: The Last Man, which stars Diane Lane. This is Vaughan's first overall deal.

"Legendary was instrumental in helping to revolutionize the way the world thought of comic book movies, so it’s a tremendous honor to work with them on adaptations of some of my and my talented collaborators' past and current comics, and I’m looking forward to hopefully creating a few wholly original stories with them as well," Vaughan said Friday in a statement.

Vaughan wrote and co-created comic hits that have won 14 Eisner Awards (the top prize in the space), as well as a Hugo Award for his work with artist Fiona Staples on Saga. His titles include Paper Girls, Ex Machina, Barrier and We Stand on Guard. On the TV side, Vaughan's credits include an Emmy nomination for his writing work on the ABC mega-hit Lost, CBS' former summer drama Under the Dome; and Y: The Last Man, which landed at FX, following a multiple-outlet bidding war after rights reverted to the creator following a years-long attempt to adapt the series as a feature. He currently serves as an executive consultant on Hulu's Marvel drama Runaways, which is based on his beloved comic of the same name. On the film side, his first spec, Roundtable, was picked up, following a bidding war, after it landed on the Black List. Vaughan is repped by Verve and Ziffren Brittenham.

Legendary Entertainment counts features including Godzilla vs. Kong, Dune and the upcoming Ryan Reynolds-led Detective Pikachu, due in May. Legendary's TV division is readying season two of Netflix's Lost in Space, a Pacific Rim anime series and Amazon's Orlando Bloom and Cara Delevingne entry, Carnival Row.

"Through truly inspired storytelling, Brian has created immersive, compelling worlds that are devoured by fans worldwide," said Nick Pepper, who joined Legendary TV Studios as president in February, after a long run at the Mark Gordon Co. "We couldn’t be more thrilled to work with Brian to bring his visions and extraordinary library of work to the screen."

The pact arrives as top creators continue to be in high demand as networks, streamers and studios alike look to lock in well-known IP and own content.
