Michael J. Fox talks alcohol abuse, denial in 'Still' documentary - USA TODAY

Fox was honored at the Governors Awards in Los Angeles on Saturday for his contributions to Parkinson’s disease research.(Nov.

Fox Movie," which premiered Friday at Sundance Film Festival, traces the life and career of the beloved"Back to the Future" star, who was diagnosed with the degenerative brain disorder in 1991.

But the actor, now 61, hid his health struggles from the public for the next seven years as he grappled privately with denial and depression.

Shooting film and TV projects during that time, Fox says he popped dopamine pills "like Halloween Smarties (candy)" to help stave off early symptoms of the disease.

Fox credits his wife, actress Tracy Pollan, and four kids for helping inspire him to get sober.

As a result of the disease, he frequently falls while walking, and gets injured multiple times while shooting the documentary.
