I honestly don't think you will get a reply from mary through her agent or manager because i sent to her agency in february of last year then a few months later i wrote to her VV at scott pilgrim vs. the world and she received the VV letter and signed my 2 pics for me but in the letter i mentioned that i had written to her at her agents address but i still to this day have never received the pics i sent to her agency and neither has anyone else on fanmail and now it says she is with creative artists who are known for not passing on mail so i think the only way you wil probably get mary's autograph is VV some time but you can try...Here are the pics she signed for me VV :

I think I got the letter thing down, let me know.

Dear Mary Elizabeth Winstead,
My name is --------- I am 23 years old and I am from the United States in the state of Florida about 15 minutes from the beach. This winter it went down to around 35 degrees and I nearly froze to death :D . I am a total nerd when it comes to video games, but I do still find time to play the guitar and work. The best game I played recently was Uncharted 2 for the playstation 3. I mainly play rock music on the guitar and I work on computer systems / design web sites. If you ever need a web site I’m your guy :D .
I have been a big fan of yours since the time I seen Final Destination 3 at my local movie theater. I am a huge fan of the Final Destination series, but number 3 will always be my favorite one. There are many reasons why it is my favorite one, but the main reason is that you did an amazing performance in it. Your performance was truly genuine and extremely passionate making it very memorable. My second favorite movie of yours is Live Free or Die Hard, which is the best action movie I have ever seen. I can never see it enough times. Even though those are my favorite I think all of your work is great and I have seen all of your movies. I am really looking forward to seeing Scott Pilgrim vs The World, it sounds like it’s going to be a great movie, but since you are in it I know it will be.
Lastly would it be possible for you to autograph the picture I have included or if you do not like that picture to send me an autograph picture of your choice? If it is not too much trouble can you personalize it To Eric. I included a self addressed envelope and an international reply coupon to pay for shipping charges. Well I better let you go I know you are very busy unlike me slacking off at work :D . I wish you the best in everything you do and I hope 2010 is amazing for you.
