Romeo & Juliet: Sealed with a Kiss is an animated feature fantasy about two star-crossed seals from warring families that fall in love against their parents' wishes. It loosely follows the traditional play, Romeo and Juliet, by William Shakespeare. It was written, animated and directed entirely by one person: former Disney animator Phil Nibbelink. The film took 4 1/2 years to make and required 112,000 frames, which were drawn by Nibbelink on a Wacom tablet directly into Flash 4, in combination with Moho.
