I think he had them when he was strapped to the chair in Arkham. The scene with Gordon and the Guard that says "Time to Play" would be the ones to rewatch for it. I don't think he had them on the Horse.
Ah, well, there ya go.
Anyway, hope the images help Shawn. It's great reference. Lots of belts, I likey.
The Scarecrow in straitjacket is definitely the way to go for this project I would say. The business suit look just isn't so threatening. But that mask on a "duster" style straitjacket with belts whipping around -- very scary.
Maybe Shawn could add wire into some of the belts so you could pose them whirling around. That would be awesome!
There's a belt at the base of his straitjacket that would be perfect to help pose the bottom of the "duster" too.
And as someone said here, the "hose" on his mask is actually a very prominent noose.
Oh yeah, and needless to say at this point, but I'd be in for one of these too. The whole straitjacket thing changed my mind about this character for my shelf.
