She's currently doing a press tour for Chappie, so unless you can find the hotels she is staying at it might be tricky

I am a big fan of "Alien" with Sigourney weaver . I would love to
have her autograph in my collection . does anyone have a Venue
address for Sigourney Weaver ? I think she is a good signer through
Venue !!! So a Venue address would be great -

I wrote to her fan mail address and never heard anything from her-

Thanks -
