When most people think of 3D movies, they imagine objects flying toward the camera (think Avatar or Journey to the Center of the Earth). Pixar took a different, more sophisticated approach with Cars. The studio utilized a technique often referred to as "natural volume" 3D.
If you just want Cars in 3D, consider:
| Title | 3D Quality | Availability | Notes | |-------|-------------|--------------|-------| | Cars 2 (2011) | Excellent (native 3D) | Common, cheap ($10–20) | Best 3D in the series. | | Cars (2006) | Good (conversion) | Rare ($40–70) | Re-release 2013. | | Planes (2013) | Good | Common | Spin-off, native 3D. |
Verdict: Cars 2 in 3D is superior to Cars 3 3D in both availability and depth.
