Hollywood actors are to boycott this month's Golden Globe Awards to show support for striking writers.
Screen Actors Guild President Alan Rosenberg said in a statement there was "unanimous agreement" among actors not to cross picket lines set up by the Writers Guild of America who are locked in a bitter dispute with film and television producers.
Rosenberg said the boycott would cover all nominees up for acting awards in the event on 13 January.
The Golden Globes is regarded as the second most important awards show in Hollywood after the Oscars.
The ban would also cover stars acting as presenters.
The decision means that nominated A-listers such as Julia Roberts, Tom Hanks and George Clooney are all likely to steer clear of the Globes, greatly diminishing one of the highlights of Hollywood's awards season.
Hollywood screenwriters have been on strike since 5 November after the WGA and the Alliance of Motion Picture and Television Producers failed to agree terms for a new contract.
Negotiations failed over the writers' demands for an increased share of profits from Internet and new media sales.
The two-month strike has forced the suspension of numerous television series as well as the postponement of work on several Hollywood films.
The WGA confirmed this week that it would mount pickets around the Golden Globes venue at the Beverly Hilton hotel.
It had already announced last month that it would not allow guild members to take part at both the Golden Globes and the Oscars.
