They say it's 1/4 scale, but I'm thinking closer to 1/5th. It's about 40 inches tall or so. I've read the full size movie Queen is between 14 and 15 feet, but that would heavily depend on where they measured the top at. With the head leaned forward, the height of the very back tip of the crown could greatly change the height measured. Although, now that I think of it, this one is stretched out a bit in it's stance, so maybe it is closer to 1:4. None of that matters to me really, but what does matter is, it is one of the few castings from the screen used rod puppet.
@ Bats - going for screen accurate, but will probably tweak to my liking.
