It was on the Toronto set of the movie Chloe that Liam Neeson first heard his wife Natasha Richardson had been in a skiing accident near Montreal. He rushed away to be by her side at the hospital, and was with her until the end, two days later.
Last week, Neeson, 56, quietly returned to Toronto to finish work on the Atom Egoyan-directed thriller costarring Julianne Moore. He shot his last scenes on Friday and the film wrapped on Saturday, Neeson’s rep confirms to PEOPLE.
