Michael Jackson's 'Thriller' is one of the most famous hit songs ever, but it was its 14-minute music video that changed the industry forever. Directed by John Landis, the video was the first of its kind to have a plot and high production values, essentially becoming a short film. It cost $800,000 to produce, which was an unheard-of amount for a music video at the time. To help pay for it, the 'Making of Thriller' documentary was sold to MTV and Showtime, inventing the 'behind-the-scenes' music documentary genre. The song features a spoken-word sequence by horror movie legend Vincent Price, who recorded his part in just two takes. The 'Thriller' album remains the best-selling album of all time worldwide. The song and video are credited with transforming music videos from simple promotional tools into a legitimate art form and a massive commercial industry.
