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.
Keiko, the Orca star of the Free Willy franchise, is back in this third adventure, which finds Willy happily acclimated to the ocean and having a child in the waters off the Pacific Northwest coast. But there's still danger out there, as Willy's human pal, Jesse (Jason James Richter), discovers when he encounters a local fishing boat illegally harvesting whales.
