'Grey's Anatomy' alum Eric Dane prepared to go to extreme measures to fight ALS

Eric Dane is prepared to go to extreme measures to fight ALS.

"I will fly to Germany and eat the head off a rattlesnake if [doctors] told me that that would help," the 52-year-old "Grey's Anatomy" alum told Diane Sawyer during a sit-down interview on "Good Morning America." "I'll assume the risk."

During the interview, which aired Tuesday, Dane opened up about the debilitating disease and explained how he's found hope in the physician who has been leading his care.
