One of Oscar night's most exclusive gatherings - the Vanity Fair party - has been cancelled in solidarity with striking writers.
The party is typically attended by the night's big winners
The magazine said that in support of the writers and "everyone else affected by this strike", it was "not appropriate" to hold the event.
Since its inception in 1994, the party has become a main post-ceremony draw for Hollywood A-listers.
It comes despite reported progress in talks aimed at ending the strikes.
A magazine spokeswoman said editor Graydon Carter had decided that even if the strike was resolved before the Oscars, the effect on Hollywood would continue to be felt.
Mr Carter said in a statement: "In as much as Vanity Fair is a collection of writers, photographers and artists, we do feel ourselves in aligned solidarity with the writers, directors and actors in the film business."
The party, held annually at Morton's restaurant, is typically attended by the night's big winners and nominees.
This year it was to take place for the first time at new Hollywood restaurant Craft after the closure of Morton's.
Other parties still scheduled to go ahead include the Governors Ball, held by the Academy Awards immediately after the ceremony.
News of the party cancellation comes after Academy Awards president Sid Ganis said there was "no doubt" the 24 February Oscars ceremony would take place.
Speaking at a luncheon to honour this year's nominees, he said that, while the circumstances of the strike were "beyond our control", the awards would go ahead no matter what.
At the weekend, the two sides made progress regarding internet and DVD payments for writers' work, the Associated Press reported.
If a deal can be reached, the Writers Guild of America could vote to call off the strike, which began in November.
Industry newspaper Variety says the strike could end as early as next week.
