During the course of his long career as an actor, Schellenberg has twice played legendary Hunkpapa Lakota chief Sitting Bull -- first in the made-for-TV movie Crazy Horse (1996) and again in the telefilm Bury My Heart at Wounded Knee (2007). The latter portrayal netted him his first Emmy nomination.
Schellenberg's most notable work on the big screen includes a central role in Free Willy (1993) and its subsequent sequels in 1995 and 1997, plus supporting parts in Iron Will (1994), The New World (2005) and Eight Below (2006). He died Aug. 15, 2013, at the age of 77.
When Jesse (Jason James Richter) meets up with the Orca friend he liberated two years earlier, an offshore oil spill forces them into another race-against-time adventure. They must band together to save Willy and his family by getting them back into the open ocean. Meanwhile, Jesse faces some of his own personal demons when his biological mother, a drug addict, dies -- and his half-brother arrives unannounced.
