Actor Kevin Costner says having his wife, children and parents on location on the South Dakota prairie while filming "Dances with Wolves" was a distraction but was worth it.

"You sometimes find yourself thinking, `I could do this better if I was by myself,' " he said in the Nov. 19 issue of People magazine.
