LOS ANGELES (AP) — The sci-fi smash "Inception" and the Facebook drama "The Social Network" have taken top screenplay honors at the Writers Guild Awards.

"Inception" writer Christopher Nolan won for best original screenplay and "The Social Network" writer Aaron Sorkin won for best adapted screenplay Saturday night at simultaneous WGA ceremonies in Los Angeles and New York.

The wins position the two writers as favorites in the same categories at the Oscars on Feb. 27.

"The Social Network," which Sorkin adapted from the Ben Mezrich book "The Accidental Billionaires," was also considered an early favorite for a best picture Oscar. But it has been trumped in recent award ceremonies by "The King's Speech."

"The King's Speech" was not eligible for a WGA award because it was not made under the union's contract guidelines.
