‘Mrs. Doubtfire’ Actor Shares 1 Heartbreaking Tip From Robin Williams: ‘I’ll Never Forget It’

Matthew Lawrence shared that the late comedian once gave him some invaluable advice.

Matthew Lawrence says he’ll “never forget” the advice of his late co-star Robin Williams.

The former child actor was only 12 years old when he starred opposite Williams in “Mrs. Doubtfire,” the 1993 classic about a family struggling with divorce. Lawrence, who played Williams’ son, told Entertainment Weekly on Thursday that they quietly bonded offscreen.

“He really explained his life to me and really brought me in and taught me not just about in front of the camera, but a lot about the behind the camera as well, and how he felt that substances really further pushed his brain to not function properly,” he told the outlet.

“And he really opened up with me, and I’ll never forget it,” Lawrence continued. “There were times he would just grab me, and he’d be like, ‘Don’t put that stuff in your body. If I could go back and tell myself, this is why I’m telling you, don’t put that stuff in your body.’”

Lawrence didn’t specify any further, but Williams had struggled with using substances like cocaine and alcohol.
