Michelle Williams is reportedly set to make a personal film about her late actor boyfriend Heath Ledger.

The actress is said to be keen to keep his memory alive for the sake of their two-year-old daughter Matilda.

A source tells the Australian Daily Telegraph, "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.

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

The proposed film will feature friends and colleagues sharing their memories of the Brokeback Mountain star.
