Natalie and Sir Anthony don't. I know those two for sure. I'm not positive about Samuel though. I just know he's an ass about signing in person even though he will sign anyways.

Hello!

I would like to know whether any of them signs authentically vv? I've read they would be hardly to get via Agency and I haven't seen any current feedbacks.
I'm planning on writing to them via a movie set and don't want to waste stamps, if it's completely hopeless ;)
Thanks in advance!
