Canadian-born Pulp Fiction screenwriter Roger Avary has pleaded guilty to vehicular manslaughter and drunken driving for a crash that killed one passenger last year.

Avary entered his guilty pleas Tuesday in a court in Ventura County, Calif.

In January 2008, Avary crashed his car into a telephone pole while driving late one evening in Ojai, Calif.

The crash injured his wife, Gretchen, and killed 34-year-old Andreas Zini, a resident of Italy who was apparently visiting the couple.

The 43-year-old writer was intoxicated at the time of the crash, authorities said. He was arrested and later released on $50,000 US bail.

In December, Avary originally pleaded not guilty to the charges. He has since apologized for the accident.

Avary — born in Flin Flon, Man., and raised in the United States — shared an Academy Award with filmmaker Quentin Tarantino for writing Tarantino's 1994 hit Pulp Fiction. He also co-wrote such films as Silent Hill and Beowulf.

He will be sentenced next month.
