I want to try to get an autograph from Milla Jovovich and others from the set of Resident Evil 6 in south africa Cape Town. They are not filming right now but they will start very soon during this month...
I know they're working with a socety called Moonlighting Films in Cape town (I contected them ) but I wanted to know if the address on their website is right and if they accept fanmail for the actors that are working with them...(They didn't answer this question) what do you think?
This is their address
337 Lower Main road , observatory
Cape Town , South Africa 7925
The problem is ...wil it work without the suite number? And how do you usually find it?
Thanks, hope to recive help
