Superhero movies very rarely get award nominations outside of tech categories. so this is quite a kudo for a movie that the much oversued descriptibe “much-loved” definitely applies.
The WGA awards are seen as an Oscar preview although they are honored in their own right.
Other nominations in the category include American Sniper, Gone Girl, The Imitaion Game and Wild. In the Best SCreenplay category the nominatiosn were Boyhood, Foxcatcher, The Grand Budapest Hotel, Nightcrawler and Whiplash.
The screenplay was not without a bit of controversy as Perlman’s contributions—an early draft in DIsney’s screenwriting program—were mostly overshadowed by Gunn, who, to be fair, has his stamp all ver the movie.
