Lego is this week launching a series of construction sets based on upcoming Hobbit movie The Desolation of Smaug.

The new Lego products range from £19.99 for the Dol Guldur Ambush set in the ruins of a fortress to £69.99 for the Dol Guldur Battle, which features six mini-figures including Gandalf and fellow wizard Radagast, along with the evil Necromancer. Completing the range are the Mirkwood Elf Army set (rsp: £29.99) and Lake-town Chase (rsp: £49.99).

Released on 13 December, the film will continue the adventure of Bilbo Baggins. The launch of the new sets follows the rollout of Lego based on the first Hobbit film last year.
