Signed Sherlock Holmes Poster - Whose signature is this?

[samdaman94]

Hey everyone

I just won a signed Sherlock Holmes poster in a competition. It's signed by Robert Downey Jr, Jude Law, Mark Strong, Rachel McAdams and Guy Ritchie. However, there is a 6th signature on the poster that's driving me nuts. It's in a different colour to the other 5 and it's tucked away in the corner. Here's a photo...

Any ideas?
Maybe it's the people who ran the competition? (Turner Classic Movies)
or maybe it's somebody who authenticated the poster?

EDIT - Nevermind, blu_sharpy got to the bottom of it - It's Kelly Reilly. Cheers sharpy!
