Mickey Fisher, an unknown and unsigned writer until recently, has film studios drooling over his script “Extant” for weeks. There’s just one twist: it’s not a film script.

Fisher wrote “Extant” as a TV pilot. It's a one-hour sci-fi drama about John and Molly Watts and their son, a human-like robot named Ethan. Molly, the space-traveling wife, is also pregnant with a baby that is part human and part alien. The family intrigue deepens in subsequent episodes.

Multiple agencies sought to sign the writer after reading the script, and WME won out. WME and manager Brooklyn Weaver, who discovered Fisher, sent the script around to the studios who are hot to trot for a high-concept script mixing sci-fi and familial drama.

"Everyone is freaking out about it," an agent at a rival firm said. "It's 'A.I.' as a TV series."

Though just 56 pages, it introduces several plotlines and interconnected characters that would be difficult to resolve in a single film. The script is written in five acts and takes place on earth and in a space station.

Warner Bros. still made an offer to acquire the project and turn it into a movie, according to multiple individuals inside and outside the studio, but now the studio is talking with Fisher about acquiring a different pitch. The studio declined to comment.

WME and Weaver always harbored dreams of turning "Extant" into a TV series with Steven Spielberg producing. They are halfway there: Amblin TV, which produced "ER" and "The Americans," is developing and packaging it. It remains unclear if Spielberg will take a credit, though his involvement would make it even more attractive to networks.

Not bad for a playwright whose lone screenwriting credits before this were “Summer Nuts” and “The King of Iron Town,” a pair of microbudget films.

Fisher is also represented by attorney Jeff Frankel.
