The Avengers assemble on Captain America Blu-ray

Captain America: The First Avenger heads to home cinemas later this year and does Marvel know how to tempt punters into a purchase? Do bears go for a number two in wooded areas?

Watching Chris Evans' supersoldier kick Nazi butt will be enough of a draw even for fans who don't salute the flag on a regular basis (fun fact: the movie did more theatrical business outside of America than it did in the US).

However, Marvel is also calling on The Avengers to assemble to seal the deal.

So while we're sure the feature commentary is worth a listen and the Marvel short is fun, it's the "exclusive sneak peek into the ultimate Super Hero team, Marvel's The Avengers " that will have fans buzzing.

Check out the trailer on the website to see brief clips of The Assembly Begins featurette.
