Jason Isaacs (Lucius Malfoy), Evanna Lynch (Luna Lovegood), and James and Oliver Phelps (Fred and George Weasley) were on hand to help preview the new Forbidden Forest expansion at the Harry Potter studio tour at Leavesden Studios.
The new Forbidden Forest expansion is a recreation of the famous film set — complete with giant trees, Buckbeak the Hippogriff and Aragog the giant spider. The expansion opens on 31 March and tickets are available from the official website.
