JUST IN: PATRICK DEMPSEY tells ET that his ABC hit "Grey's Anatomy" is not prepared for the pending Writers Guild of America strike. <br /><br />While promoting his new film 'Enchanted,' he told ET's THEA ANDREWS, "The problem is that we're not that far ahead scriptwise. I think we'll have enough shows that take us through Christmas, and after that we'll see if that's the season or not." <br /><br />When asked if Hollywood is looking at a virtual shutdown, he said, "I think there's a real chance of that happening. It's going to be very bad for television, certainly. The season will be wiped out if [the strike] continues for too long." <br /><br />The star also expressed deep concern for crew members and those in the Hollywood community. <br /><br />"My concern is not so much for myself really, because I'll be alright, but I think how long this strike lasts is going to affect a lot of people that are living paycheck to paycheck -- they are going to be damaged profoundly by this, and I think that's a real tragedy," he said. "I think a lot of people and a lot of families are going to be in a difficult place in their lives; hopefully we can come to some sort of understanding and resolve this soon enough that it doesn't affect those people." <br /><br />Unless an agreement can be reached, the strike is expected to begin Monday. <br /><br />For more, stay tuned to ET!
