Something else to talk about

[laurenmcoakley]

So, I recently viewed some pictures on veritaserum.com, and saw Emma 
Watson with her stand-in, who really does look a lot like her.

I also viewed a photo of Rupert with his stand in, who, at least 
facially, does not (IMO) look very much like Rupert.   
http://wickedschmuck.zftp.com/RGMS_ORG_2005_decio_grint.jpg (From 
www.RGMS.org) And that is a wig his stand-in is wearing, BTW.

Does someone have any idea what it is that a stand-in does exactly?  I 
undertand fully what a STUNT double is, but not a body double or stand 
in.
