Amazon.co.uk offers Reel Heroes Box Set on Blu-ray Disc for $13.72 (£8.50). At final checkout it drops to $11.43 (£7.08). With $4.97 (£3.08) for shipping, that's $29 below the lowest total price we could find the US versions of these movies on Blu-ray disc purchased separately elsewhere. This 4-disc set features Scott Pilgrim vs The World, Wanted, Hellboy II, and Kick-Ass. It's listed as region-free.
Of note, although the movies themselves will play on US Blu-ray players, the extras and special features may not.
