The actor's 31-year-old nephew, Ronan Sexton, fell 20 feet from a telephone box onto the pavement in East Sussex, Britain, and is in critical condition with head injuries. Sexton, the son of Neeson's sister, Bernadette, had been out with friends when the stunt went wrong about 4am Sunday, reports the Telegraph. Earlier this year, Neeson said the death of Natasha Richardson still didn't seem real.
