In that demo as well as others, "Liz & Dick" was the year's fourth most-watched original movie premiere on ad-supported cable, behind the Lifetime movies "Steel Magnolias" (which drew 6.5 million total viewers with its October premiere), "Drew Peterson: Untouchable" and "Abducted: The Carlina White Story."
Compared to all of Lifetime's original movies this year, "Liz & Dick" was up 40 percent in total viewers, and 41 percent in the 18-49 demographic.
The network will run an encore of "Liz & Dick," which was executive-produced by Larry A. Thompson, directed by Lloyd Kramer and written by Christopher Monger, at 8 p.m. Monday.
