As purplemonkey wrote, you can't do that. They have nothing to do with the filming. When you write via-venue, you use different address. This address is of the place where the filming is done. How to get the address? You can find it on the internet or request it at [url=http://www.fanmail.biz/mboard/viewforum.php?f=124][b]Add / Request a 'Via Venue' Address[/b][/url].
And if you're looking for the address of Breaking Down...I'm pretty sure it'll be closed set. That means that they won't forward any mail and it'll just end up in rubbish unless you know someone who works there so they can forward your mail on. Plus VV addresses of Twilight Saga movies are really hard to find.
If you don't understand anything feel free to PM me or write it down in this topic.

Summit Entertainment is the distribution company, so they have no direct relation to actual filming of the movie. They just get the movie released. So in saying that distribution company's do not pass on mail.

So i'm new to this process can someoen explain? So I pick a studio~ for an example we'll say Summit entertainment cause I really want Taylor Lautner's right now! I'd send it to them and while he's filming breaking dawn they'd pass it on? Do I understand this correctly? Please help.
