The video for a-ha's "Take On Me" used a pencil-sketch animation / live-action combination known as rotoscoping, in which the live-action footage is traced over frame by frame to give the characters realistic movements.
Approximately 3,000 frames were rotoscoped, which took 16 weeks to complete. The video cost $150,000 USD, which was significant at the time in 1985.
Actress Bunty Bailey, who played singer Morten Harket's love interest, went on to star in the band's follow-up video, “The Sun Always Shines on T.V.,” and had a real-life romance with Harket.
The iconic music video for “Take On Me” has reached one billion views on YouTube, a feat very few artists have accomplished.
