Hard just to choose one but it would probably be Japanese T2 premium. I love the clean silver look and the embossed front. Inglourious Basterds (Canada), Pulp fiction, Fight Club and Watchmen (Canada) would also be up there as my favourite's!
Toss up between Princess and the Frog CA Ironpack and the War of the Worlds german steelbook ...course any of the Disney steelbooks are great too!! decisions decisions
It's hard to choose. Probably my best looking steels are the Disney's especially Beauty and the Beast and Alice in Wonderland and the Korean Avatar. My favourite movie in a steelbook is Inception.
Transformer Revenge of the Fallen (Canada) is still one of my favourite Steelbooks. Even if it was a pretty bad movie the art is enough to make me buy it.
Inception recently is a pretty nice looking steelbook.
