Ferrell talks about hairier days

For "Semi-Pro," Will Ferrell grew out his own naturally curly hair to try to evoke the look of such ABA players as Julius Erving and Darnell Hillman."That's really my hair," says the former "Saturday Night Live" standout. "My hair actually does that when not cut for six months."He continued: "I just got my hair cut recently, and that's when my oldest son (Magnus, 4) was like, 'Papa, your hair -- what happened?' I didn't detect sadness. He was just like, 'Your head looks different.' "The actor also has a 14-month-old son, Mattias.Ferrell says his wife, Viveca, liked his ultra-long curly locks."She loves the long hair," he says. "She's one of the few people who like it. Everyone else is like, 'What's going on?'"I remember I ran into Nicole Kidman at the Oscars (in 2007), and she looked at my hair, and I'm like, 'Oh, I'm growing it out for a part.' She's like, 'Obviously!' I was like, 'Oh, don't say it like that.' "(Contact Betsy Pickle of The Knoxville News Sentinel in Tennessee at www.knoxnews.com.)
