How many years did it take to make the movie gnomeo and Juliet?

While I don't have access to the specific production timelines for movies, I can tell you that the production process for an animated film like *Gnomeo and Juliet* usually takes several years.

This includes:

* Pre-production: Scriptwriting, storyboarding, character design, voice casting, and animation planning.

* Production: Animation, modeling, texturing, lighting, and rendering.

* Post-production: Editing, sound design, music composition, and special effects.

Consider that *Gnomeo and Juliet* is a feature-length animated film, which requires a considerable amount of time to complete all these steps.
