Beverly Hills, Calif. ? “No Country for Old Men” and “There Will Be Blood” led with eight Academy Awards nominations each Tuesday, among them best picture and acting honors for Daniel Day-Lewis and Javier Bardem – but it remained in doubt whether any stars would cross striking writers’ picket lines to attend the ceremony.

“No Country for Old Men,” a crime saga about a drug deal gone bad, and “There Will Be Blood,” a historical epic set in California’s oil boom years, will compete for best picture against the melancholy romance “Atonement,” the pregnancy comedy “Juno” and the legal drama “Michael Clayton.”

Awards shows have become casualties of the strike by writers, whose union leaders say they will not allow members to work on the Oscars. Nominees already are saying they would stay away in support of writers if the strike lingers until Oscar night Feb. 24.

“I wouldn’t do that. I couldn’t. I come from a tradition of not crossing picket lines,” said Tom Wilkinson, a supporting-actor nominee for “Michael Clayton.”

“Atonement” and “Michael Clayton” trailed with seven nominations each, including best actor for George Clooney in the title role of “Clayton.” The lead players in “Atonement,” Keira Knightley and James McAvoy, were shut out on nominations, however, with teenager Saoirse Ronan the only performer nominated for that film, for supporting actress.

Past Oscar winner Cate Blanchett had two nominations, as best actress for the historical pageant “Elizabeth: The Golden Age” and supporting actress for the Bob Dylan tale “I’m Not There.”

On strike since Nov. 5, the Writers Guild of America refused to let its members work on the Golden Globes, which prompted stars to avoid the show in solidarity. Globe organizers were forced to scrap their glitzy telecast and instead announce winners in a swift, humdrum news conference, without anyone on hand to accept the prizes.

If guild leaders follow through and refuse to let writers work on the Oscars, it would leave nominees and other celebrities forced to choose between attending the biggest night in show business on Feb. 24 or staying home to avoid crossing picket lines.

“I would never cross a picket line ever. I couldn’t,” said Tony Gilroy, a directing nominee for “Michael Clayton.” “I’m a 20-year member of the Writers Guild. I think whatever they work out is going to be one way or the other but no, I could never cross a picket line. I think there’s a lot of people who feel that way.”
