"We Believe" movie premier. 6/12 Chicago. Help needed!

[Wooter420]

So I'm planning on hitting up the movie premier for the movie"We Believe".
Its about Chicago's love of the Cubs. Many native Chicagoans are featured along with many past & current Chicago Cubs players/coaches.

Appearing at the premier will be:
Gary Sinise
Dennis Franz
Jeff Garlin
Hugh Hefner
Joe Mantegna
Bonnie Hunt
Buddy Guy
Billy Corgan
Bud Selig
Bob Costas
Past/present Cubs players & coaches

The red carpet arrival starts @ 6pm. I figure ill be there around 2pm.
Before I get all my photos printed for this, who is & is not a good signer on this list? I'm mostly foing for Sinise,Hefner,Mantegna,Guy,Corgan & a few Cubs players.

Thanks for all the help!
