Trivia
Christopher Lee is semi-related to Bond author Ian Fleming: his mother married Fleming's uncle Harcourt Rose while he was a child, therefore the relation is not by blood. In the years before Fleming's death, Lee was commonly his golf partner.
Prior to Scarmanga, Lee was offered and accepted the role of Dr. Julius No in the very first Bond film, but the filmmakers instead went with Joseph Wiseman.
Initially a star of the Hammer horror films of the 50s and 60s (particularly in the role of Dracula), Lee relished his role as Scaramanga in breaking type from his repetitive roles in the horror genre. After Bond, Lee would have a prominent film career in several other notable film series, including Count Dooku in the Star Wars series and Sauruman the White in the Lord of the Rings trilogy, as well as appearing in several films by director Tim Burton.
