Reese Witherspoon is so determined to help her brother, John, who was convicted of sexual assault in 2002, that she has hired him as her assistant on the set of her new movie, Our Family Trouble. The Oscar winner's husband, however, is not comfortable with the arrangement. A friend says, "Ryan is seething. He doesn't like John." John Witherspoon served two years' probation for aggravated burlary and sexual battery after sneaking into a neighbor's house and molesting her as she slept.
