Paris Hilton turned down the role of Lucy Ewing in the new Dallas movie, because she's not ready to take on such a big role.

The hotel heiress made her movie debut in House Of Wax, Hilton wants to cut her teeth in smaller films before she hits Hollywood's blockbusters.

She says, "I was a huge fan of the show and never missed it when I was a kid - more for the hair and fashions than the storylines."

"But the truth is the role is too demanding for me. I told them I need to make a few more smaller movies first, then take it from there."
