Actress Michelle Williams is planning to produced a documentary based on the life of her late ex Heath Ledger. The film would feature friends and colleagues sharing their memories of the Oscar-nominated star.

“It makes Michelle’s heart ache that Matilda was so young when Heath died and she’s unlikely to retain any memories of her father,” a tattle spilled to Australia’s Daily Telegraph on Friday.

“She (Williams) wants to keep his spirit alive with something Matilda can treasure all her life.”
