THE earth moved for “10.5” Sunday night.

The first part of NBC’s earthquake movie notched 20.4 million viewers from 9 to 11 p.m. – the best viewership numbers for any TV movie in over two years.

It also notched the highest rating in the coveted 18-49 demo for any NBC movie in over five years – since “Noah’s Ark, Part Two” in May ’99.
