The Writers Guild of America revealed its annual award winners in film, television, and other media on Sunday evening, crowning some critical darlings and providing a potential shakeup to the Oscars race.



On the television side, Atlanta" took home two trophies, for best comedy and best new series, continuing its recent successful awards season run. And fellow FX series "The Americans" nabbed the prize for best drama series, finally gaining some awards attention after its excellent fourth season. (Its only previous WGA nomination came in 2014, for best new series.)



But the real story was on the film side of the equation, with "La La Land" losing out on one of the night's top two prizes. A nominee for best original screenplay, the musical was instead upstaged by "Moonlight," which took top honors. "Arrival" was named the other big winner, taking the best adapted screenplay award.



In an odd bit of category confusion, "Moonlight" and "La La Land" will not go head-to-head in the screenwriting category at the Oscars, with "Moonlight" landing among the Academy's adapted screenplay nominees (alongside "Arrival"), and "La La Land" nabbing an original screenplay nod. But they're both vying for Best Picture, and "La La Land" seems to be losing its once seemingly unstoppable momentum; could this latest setback spell trouble for its chances to take home Oscar's biggest prize?



A partial list of WGA film and television winners is below. For the complete list of honorees in all categories, visit the WGA website.
