Even in 2012 there are a number of classic films that have yet to be released on Blu-ray, but we can knock one off that list March 6th when Monty Python and the Holy Grail comes home from Sony Pictures. Beyond being remastered in HD and featuring a 5.1 DTS-HD MA soundtrack, the release will also bring exclusive Lost Animations, extended scenes and outtakes features running for over 30 minutes. iPad owners will also be able to snag a companion Second Screen app called The Holy Book of Days that includes special background content from each of the 28 days of the movie's filming. It will cost $4.99 on its own, but for a "limited time" there's a $5 rebate available for those who purchase both disc and app. The disc comes with an Ultraviolet Digital Copy and has an MSRP of $19.99, but Amazon's preorder pricing is already down to $12.99. Check out the full list of extras in details in the press release after the break, and if you're not already familiar with the airspeed velocity of an unladen swallow (African or European) we've included the old DVD trailer from a few years ago as well.
