Liam Neeson has turned down a movie role because he’s still grieving his wife Natasha Richardson‘s death. When Richardson died following a skiing accident last March, Neeson was already signed up to star alongside Jeremy Irons in a new film by Scottish director Norman Stone, about Saint Columba, who brought Christianity to Scotland. Stone said he waited several months to see if Neeson felt ready to take on the role. “It has been a difficult time for Liam,” said Stone. “I think he would have been great in the film. We wanted him to play the part of King Aidan, who has fiery clashes with Columba (Irons)… The script was with him for several months and I understand he loved it. He has decided not to go ahead, which is a pity, but the decision was made after what has been a difficult time for him and I respect the circumstances. He is a truly great actor.” At the time his wife died, Neeson was filming Atom Egoyan‘s Chloe, which opens March 26.
