Warner Bros. has inked a deal with “Devil’s Advocate” scribe Jonathan Lemkin to pen the sequel to the studio’s 1996 blockbuster, “Twister.”

Lemkin, a former TV writer who also worked as a staff writer at Warner Bros. doing uncredited polishes on such pics as “Demolition Man,” will script an original sequel to the hit disaster pic. The original film took in $242 million at the domestic box office, and $252 million internationally.

While plans for the sequel has been hinted at, and even assumed, Lemkin’s hiring cements Warner Bros.’ interest in the project. WB co-president of worldwide production Bill Gerber struck the deal on the studio’s behalf.

“Twister” was directed by Jan De Bont and was produced by Kathleen Kennedy, Ian Bryce and Michael Crichton.

Kennedy also will produce the sequel, along with Steven Spielberg’s Amblin Entertainment.

Warner Bros. handled domestic distribution on the original and Universal took foreign; after costs, the two studios split both U.S. and overseas returns 50-50.

The two studios jointly purchased the “Twister” spec script, written by Crichton and his wife Anne-Marie Johnson, for an estimated $2.5 million in 1994. It’s unclear what Universal’s role will be in the sequel.

Details of Lemkin’s deal were not available. The scribe is repped by CAA’s Adam Kanter and Tori Metzger.
