LEGO BIONICLE: Takanuva and Makuta commercial (found English version of toy commercial; 2003)
September 16, 2003 saw the release of BIONICLE: Mask of Light, the first of four direct-to-video movies spun off of the Lego BIONICLE toyline. This movie introduced a new member of the heroic Toa Nuva warriors: Takanuva, the Toa of Light. It also marked the first time the franchise's main antagonist, Makuta (later known as Teridax), made a personal appearance in a BIONICLE story. Naturally, Lego started selling toys of both characters around the time of the movie's premiere. Unfortunately, the English version of the commercial for the toys has not appeared online-only the French version.
Update 08/04/2016: After contacting Lego's Customer Service about the commercial the day before, a LMW user received the following reply:
"I tried to find the 2003 Titan commercial in English for you, but you've probably already looked everywhere I can! I found the one in French you mentioned, and found other commercials in English. Sadly, I wasn't able to locate the Bionicle Titan one for you. My apologies that I wasn't able to help you with that."
