Lawrence was just 12 years old when he starred alongside Robin Williams in "Mrs. Doubtfire," the heartwarming hit about a devoted dad who transforms into a Scottish nanny to stay close to his kids following a divorce. Now 45, the actor says those memories, and Williams’ voice, have stuck with him ever since.

As the '80s progressed, Robin Williams ramped up his acting career, with roles in movies like The World According to Garp, Moscow on the Hudson and other films. He soon proved that he was more than just a jokester, when he was nominated for an Oscar for his role as a '60s-era DJ in the 1987 film Good Morning, Vietnam.

Mrs. Doubtfire' star Matthew Lawrence wants to use AI to resurrect the voice of his late co-star Robin Williams.
