Neville, who was suffering from Alzheimer's disease, died Saturday in Toronto surrounded by family. The Stratford Shakespeare Festival, where Neville worked as an artistic director in the 1980s, announced his death in a statement over the weekend.
Neville appeared in dozens of movies, television shows and theater productions during a career that spanned six decades.
Perhaps the one that gave him the most prominence came in the '90s when he landed the recurring role of the "The Well-Manicured Man" in the "The X-Files."
Neville was born in England, emigrated to Canada in 1972 and later became a citizen.
