The Producers Guild of America has announced its nominations with The Curious Case of Benjamin Button, The Dark Knight, Frost/Nixon, Milk and Slumdog Millionaire as contenders for PGA’s top feature award.

The PGA’s announcement appears to be of the norm with nominees for its Darryl F. Zanuck Producer of the Year Award include Kathleen Kennedy and Frank Marshall and Cean Chaffin for Benjamin Button; Christopher Nolan, Charles Roven and Emma Thomas for The Dark Knight; Brian Grazer, Ron Howard and Eric Fellner for Frost/Nixon; Dan Jinks and Bruce Cohen for Milk; and Christopher Colson for Slumdog Millionaire.

The group also announced its documentary feature nominees, which the category was launched last year. The nominees are Simon Chin for Man on Wire, Julie Bilson Ahlberg and Errol Morris for Standard Operating Procedure (a Screenhead giveaway), and Carl Deal and Tia Lessin for Trouble the Water.
