An Oscar-winning screenwriter of "Pulp Fiction" has pleaded guilty to vehicular manslaughter and drunken driving for a crash that killed a passenger in his Mercedes.

Roger Avary of Ojai, Calif., entered the pleas Tuesday in a Ventura, Calif., court. He'll be sentenced next month and remains free on bail.

Authorities say the 43-year-old was intoxicated when his car hit a telephone pole in Ojai on Jan. 13, 2008. The crash injured his wife and killed 34-year-old Andreas Zini, who was visiting from Italy.
