VIDEO: Michelle Williams Opens Up About Heath Ledger's Death

Almost three years after the death of Heath Ledger, Michelle Williams opened up about the loss of her ex-fiance.

"In a strange way, I miss that year, because all those possibilities that existed then are gone," she said in an interview with Nightline. "It didn't seem unlikely to me that he could walk through a door or could appear behind a bush. It was a year of very magical thinking, and in some ways I'm sad to be moving further and further away from it."

Williams met Ledger in 2005, when they played husband and wife in Brokeback Mountain, and the couple soon had a daughter together, Matilda. Though they separated a year later, they remained close until Ledger's death, from an accidental prescription drug overdose, in January 2008.

The actress is currently starring in Blue Valentine with Ryan Gosling, who was also interviewed in the segment. —ISHITA SINGH
