You might want to hold off buying that Batman DVD just a little while longer.

Although The Dark Knight will be available for home video starting this Tuesday, the movie will soon be hitting a much larger screen. Starting January 23rd, the second-highest domestic grosser of all time will once again be entering the multiplexes.

Why now? Well, there are two very good reasons. Those who don’t recognize the significance of the “premiere” date should know that it was chosen for a reason. January 23rd just happens to fall one day after the Oscar nominations are announced. Could Warner Bros. be planning on a posthumous nod for Heath Ledger? If so, a re-release could remind voters of this summer’s most noteworthy performance.

And the second reason? Money. Knight is very close to reaching the $1 billion mark. Another $4 million will put the blockbuster in a group currently occupied by Titanic, The Lord of the Rings: The Return of the King and Pirates of the Caribbean: Dead Man’s Chest.
