Miramax Films and Sony Pictures Classics nabbed a pair of nominations each in the WGA Awards' documentary writing category, while Lionsgate figured in another of the category's noms.
Those nominated included:
"Deliver Us From Evil," written by Amy Berg, Lionsgate.
"The Heart of the Game," written by Ward Serrill, Miramax.
"Once in a Lifetime: The Extraordinary Story of the New York Cosmos," story by Mark Monroe and John Dower, screenplay by Mark Monroe, Miramax.

The WGA's inaugural docu award went to Morgan Spurlock's "Super Size Me" in 2005, and Alex Gibney won the award last year for "Enron: The Smartest Guys in the Room."
"Since the creation of the award, there has been a more than 50% increase in U.S. documentaries containing a writing credit," the WGA said.
About 35 films were submitted for consideration this year, representing a 40% increase compared with last year, officials said.
Winners in all categories of the WGA Awards will be announced at the guild's annual gala, set for Feb. 11 with simultaneous ceremonies to take place at the Hyatt Regency Century Plaza in Century City and the Millennium Broadway Hotel in New York.
