It’s just an incredibly sculpted action figure from NECA, the first of its Princess Bride line. Although in all honesty, it’s not a toy of the Dread Pirate Roberts either, since it’s actually of the farm boy Westley, disguised as the Dread Pirate Roberts.
Man, when The Princess Bride first came out, I would have killed one of my fellow sixth graders to get action figures of the movie. Now? I can patiently wait until NECA releases the toys this spring, and I can kill sixth graders just for fun. If I recall properly, the other two figures in the first wave are Buttercup and Inigo Montoya, but I’ll let you know if I hear otherwise.
