The comedy-friendly director likes to incorporate odd and humorous images into his films, and Thor: Ragnarok is certainly no exception.
As he admitted in the commentary track, Waititi bought a shake weight while working on 2011’s ill-fated Green Lantern and kept it throughout the years, apparently.
While one would think that this is simply any old shake weight, it is apparently the one owned by the director himself.
One such example is the scene where Skurge, played by Karl Urban, is seen holding a shake weight with menacing intensity.
