PCL LinkDump posted about this fun, tripped out Man from U.N.C.L.E. fan fiction staged with dolls.
Evidently, the good folks at Tonner Doll Company have whole worlds of character dolls. Including characters from Firefly.
Yes, Mal (browncoat sold separately), Inara (sold out), Zoë and the man they call Jayne.
No sign of/word about Wash, Book, Kaylee, Simon or River Tam. And as these are figure dolls, probably no chance of there being a scale model of Serenity.
