There was never just one Bourne DVD.
Universal will announce today that The Bourne Legacy is coming to DVD, Blu-ray Combo Pack, On Demand, and digital download December 11, 2012. The thriller follows agent Aaron Cross (Jeremy Renner) as he fights to survive an epic, twisty game of cat-and-mouse — following in the footsteps of his predecessor, Jason Bourne. Edward Norton and Rachel Weisz also star. Special features include a variety of making-of featurettes, a set of deleted scenes, and commentary from director/co-writer Tony Gilroy.
I have no intention of putting this horrible film in my library, but if you are interested, well, there you go.
