The quote 'Inconceivable!' is the catchphrase of Vizzini in 'The Princess Bride.' To give the film its unique 'storybook' feel, composer Mark Knopfler used the Mellotron. The Mellotron is an early sampling keyboard that uses magnetic tape loops of real instruments. Its slightly 'warbly,' imperfect orchestral sounds matched the film's charming, self-aware aesthetic. Rather than a modern, polished orchestra, the Mellotron provided a nostalgic 'hand-made' quality that became part of the movie's legend. This choice proved that vintage technology can be used to create a timeless atmosphere that digital sounds often can't replicate, making the adventures of Westley and Buttercup and their romantic dialogue feel like a classic, cozy dream.
