Actor Peter O'Toole and his ex-girlfriend have renewed their legal fight for custody of their 5-year-old son, Lorcan. O'Toole testified behind closed doors Wednesday in Freehold, N.J., giving what was described as "fairly emotional" testimony by the lawyer for the child's mother, Karen Somerville O'Toole.

At issue are changes in a previous joint custody agreement under which the actor and the mother, who uses O'Toole's name even though they never married, alternated custody of the boy every three months. In April O'Toole failed to return Lorcan to his mother as scheduled after a London stay.
