Hi, I am new and I have a question about sending mail to a movie that is currently in production. If I wanted to send a photo to Tim Allen at the set of the new Santa Clause Film.....how would I address it to him? Also, I think it said that the movie is going to start filming in November, there is already an address for the set. Should I send the photo now, or should I wait until November when they start to shoot the movie?
Thanks.

I would wait to send the letter until it has started filming. When writing to Tim Allen through a movie set start the address like this:

Tim Allen
'Santa Clause 3'
(and then the rest of the address)
