The London Tree of Souls is one of the nerdiest displays of Avatar fandom yet (and I broke the story on P.A.D.D. -- post Avatar depression disorder -- on Trend Hunter).
The London Tree of Souls was a one and done event held in Hyde Park, meant to coincide with the release of Avatar and the Earth day holiday. Stephen Lang, who played Colonel Miles Quaritch in the film, was on hand to gawk at the Avatar super fans who showed up in full force.
