Downey took to Facebook to share a special tribute to his late mother

In a Facebook post on Friday (Sept 26th), Downy firstly recognized his mother's projects she and his father, director Robert Downey Sr., did together, which included 'Greaser's Palace,' a flick about a woman who is silently persecuted by God.

"By the mid '70s, the downside of drug culture caught up with many artists. She was an alcoholic," Downey wrote. "As the marriage suffered, she continued to work, but not for long. A recurring role on Mary Hartman, Mary Hartman' ('76-'77) was her last paying job...not that she cared, she'd have done it for free."

After becoming sober, she inspired her struggling son to do the same.

"While I strived to have the kind of success that eluded her, my own addiction repeatedly forbade it," he continued. "In the summer of 2004, I was in bad shape. She called me out of the blue, and I admitted everything. I don't remember what she said, but I haven't drank or used since."

Downey also remembered his mothers' final years of her life, which she spent with him and his family in Los Angeles while being very ill. "Many fond memories of her in the last few years...holidays, kid-stuff, her strutting around with a walking stick. I knew it was difficult, and understood as the visits got shorter."
