THE BEST
#1 - Johnny Depp - Sorry to do this to Morgan but after the way Depp signed at Dark Shadows premiere and Kimmel he owns the number one spot.
#2 - Olivia Munn - Simply put, once of the nicest women in all of Hollywood. A truly great signer.
#3 - Jeffrey Dean Morgan - If it wasn't for Depp and Olivia, Jeffrey would run away with this but as is he is still one of the coolest people you will meet on the other side of the barricade.
#4 - Jon Bernthal - I named him the best signer of 2011 and 2012 has brought more of the same. He is quite simply one of the nicest celebrities I have ever met and would be higher on the list if I saw him more.
#5 - Milla Jovovich - Signed for close to 30 minutes at Resident Evil premiere. Outsigned all photos. Took photo with anyone who asked. How could she not be on this list?
#6 - Andrew Lincoln - On consecutive days signed more autographs than some celebrities sign in a year.
#7 - Matt Bomer - The White Collar star has signed every single time I have met him and is always in a good mood while signing.
#8 - Pauley Perrette - Signs every time I see her and signs multiples and will talk to you and take photos with you.
#9 - Ron Perlman - My criteria is someone who signs every time I see them, including multiple times on the same night, belongs on this list and that is Ron.
#10 - Michael Shannon - This guy racks every time I see him, signs multiples and signs full signatures. Nice guys go far in Hollywood and hope it happens for him.
THE WORST
#1 - Hugh Laurie - In a crowd won't sign. One on One won't sign. Simply a horrible signer and damn near impossible to get for along time.
#2 - Kristen Stewart - Unless you look like a crazed, rabid teen-age girl chances are your experience with this actress will be horrible.
#3 - Charlize Theron - I honestly can't envision anytime in the near future where she will be a good signer. She will be on this list for a long time.
#4 - Lindsay Lohan - I have seen her ten times in the last month and never even came close to getting her autograph.
#5 - Joseph Gordon Levitt - While this guy simply refuses to sign autographs I do give him credit for not being rude about it.
#6 - Vanessa Hudgens - When you can't even get someone to sign at their own premieres chances are you won't get them to sign anywhere.
#7 - Kate Upton - Based on my last experience with her I will never, NEVER, go out just to try and get her autograph.
#8 - Sophia Bush - Simply put, is almost impossible to get to sign here in Los Angeles.
#9 - Liam Neeson - Not rude about it but simply states he longer signs autograph.
#10 - Colin Farrell - Just comes across as so arrogant. He is an angry signer.
