Harry Potter finally made its return to Lego in 2010, after five years of absence in which it was sorely missed by fans. With six sets in the initial wave, the largest and most distinctive is the iconic building, Hogwarts Castle.

Lego has produced 3 previous versions of the famous castle over the years (interestingly coming out every 3 years from 2001 onwards) but this latest one is without a doubt the definitive version. At 1290 pieces and with 10 minifigures it is the largest Harry Potter Lego set ever, having almost double the amount of pieces as the original castle.

New figures in this set include Professor Flitwick and Argus Filch (along with his creepy cat Mrs Norris). Other figures include Lord Voldemort , Professor Dumbledore , Professor Snape , Professor McGonagall, Harry Potter, Hermione Granger and two Dementors.

Rather than having the set coming from one film, it seems to cover a few different films. For example, it features appearances from "He Who Must Not Be Named", who only came to Hogwarts in the final book, as well as a tile featuring Sirius in the fire (from the fourth film). Other notable features include a printed Sorting Hat, Gryffindor's Sword (silver!), a Basilisk fang, Harry's invisibility cloak, sliding stairs and too many more to mention.

There are features aplenty in this set and, for true fans of Lego and Harry Potter, an amazing amount of unique printed pieces. Notable amongst them - a copy of The Marauder's Map, The Daily Prophet ("Mass Breakout From Azkaban"), The Qubblier ("Harry Potter Speaks Out At Last") and the Hogwarts Crest.

While there are a number of great printed parts there are also stickers (but not too many) including ones for a shield featuring the name of Harry's father, James, as Gryffindor Seeker and the Slytherin and Gryffindor great hall hangings. The school owls and Mrs Norris all come with fully painted faces as does the Sorting Hat and many of the figures some with full torso printing, leg printing and/or double sided head pieces.

Rooms include Dumbledore's office, the restricted section of the library, the Room of Requirement (featuring a vanishing cabinet), the astronomy tower, Slytherin and Gryffindor common rooms and of course the Great Hall complete with food and seating areas.

Honestly there is so much playability in this set and Harry Potter fans will go crazy over the amount of detail the designers have put into this latest (and last?) castle. Lego have really outdone themselves here and set 4842 is well worth the $129 price tag. I imagine this set will sell like Chocolate Frogs.
