A “Battle of the Nutcrackers” week on Ovation begins with a surrealist 2006 version by Mikhail Chemiakinas from Saint Petersburg, Russia, “Marinsky Theatre’s The Nutcracker” (Ovation, 8 and 10:15 p.m.).

In the tradition of reality TV, each night’s dance will be scored by Nigel Lythgoe and Debbie Allen of “So You Think You Can Dance,” whose reruns not coincidentally air weekends on the arts network.

Viewers will be able to vote for their favorite as well, with the winner getting a replay on Christmas Eve. A Mark Morris production has won three of the past four years; last year’s winner was the Royal Opera Ballet.
