Actor Joshua Jackson's first TV role since the end of DAWSON'S CREEK in 2003 has been put in jeopardy by the Hollywood writers' strike. Jackson was to have guest-starred as a doctor in several upcoming episodes of Grey's Anatomy, but producers have now had to scrap the idea. However, TV bosses hope to recast Jackson in another role after the strike ends. The Writer's Guild Of America called on its 12,000 members to stop working in early November (07) after representatives failed to resolve a dispute over royalties.
