My copy of the Batman: DC Super Heroes Unite on Blu-Ray/DVD arrived from the US via the Amazon.co.uk marketplace yesterday.
I can confirm that the Blu-Ray disc is not region coded and played just fine on my UK player. I didn't try the DVD.
The movie is about 70 minutes long and I'd like to tell you that I enjoyed it but to be honest I found it a bit boring and only watched the first 20 minutes of it last night. There's no doubt it looks stunning but it's nowhere near as entertaining as the Star Wars ones, particularly the Padawan Menace.
The main reason for buying it, of course, is for this minifig, Clark Kent in a transitional state, which as you can see looks great. Clark is sporting the same hairstyle as Robin and a number of other recent minifigs. The head printing isn't the best I've seen but looks fine from a short distance.
It's a figure every Super Heroes collector will want and thankfully it's not too hard to get hold of it. The comments on this news article suggest it's available in quite a few places but, alas, not in UK shops...
