A couple of weeks ago Shaun mentioned a Harry Potter chess set that fans can eventually complete by buying individual magazine issues. For Potter fans with deeper pockets, you could also buy a "Hogwarts House Quidditch Chess Set". Made of hardwood with 24K gold plating, that's bound to cost a small fortune.
If that's not enough, and you have a little more dough, there is also the Final Challenge set - a replica of that one used in "The Sorcerer's Stone".
While we're talking movies, you just have to go and see the Transformers movie - definitely the coolest movie so far in 2007! There's a chess set for this too.
