Jake Lloyd (Young Anakin Skywalker): Don't try the address on this website. An address you use on a website you have to pay for might work, though.
Natalie Portman (Padme Amidala): The address on this website is in France, so you may have trouble with the postage to begin with, but in the end, no address will work with her. She is rather stubborn about autographs.
Ray Park (Darth Maul): He won't respond to the address on this website, but you might get something from an address on another website.
Liam Neeson (Qui-Gon Jinn): May or may not respond via venue
Hayden Christensen (Anakin Skywalker): No one has had a success with the address on this website. Try an address on a different website.
Ian McDiarmid (Emperor Palpatine): He's the same as Natalie Portman; unless you can find a supernatural address, you'll get nothing.
Samuel L. Jackson (Mace Windu): You can get a pre-print for free from celebritymerch.com
Ewan McGregor (Young Obi-Wan Kenobi): You may receive a pre-print. I myself had a success with him, but no one has in a year or so. Still, try if you haven't!
Felicity Jones (Jyn Erso): She has been generous with autographs in the past, but after Rogue One, she slowed down and maybe quit. Try her when Rogue One has died down. That's what happened with Oscar Isaac (read below).
Ben Mendelsohn (Director Krennic): He's almost impossible to get. Don't try using the address in the database. People have had successes with him via venue.
Harrison Ford (Han Solo): If you use the address in the database, you may receive an Indiana Jones pre-print. However, using a certain address from a different website, I got two nicely finished 5x7 pre-prints in three months! It's very rare, but he may reply vv. If you want a real autograph, try sending a picture of him NOT as Han Solo. You're more likely to get a reply if you send a picture of him NOT as Han Solo.
Peter Mayhew (Chewbacca): You can buy an autograph on his website, chewbacca.com.
Mark Hamill (Luke Skywalker): In 2016, people had successes with him by using the address in the database until the fall. It's unlikely he'll respond vv, but that's not a definite, "No." Maybe people quit sending requests because it seemed he had stopped, but maybe there's really a small pile of autographed photos ready to be sent!
James Earl Jones (Darth Vader voice): He used to be super friendly with autographs and always respond, but lately, people have received their photos and letters back with a note that says he's overwhelmed with autograph requests and doesn't have time to respond. It was suggested he does an on-off thing, where he signs for one month and then not the other two. Personally, I heard that after getting the "overwhelmed with autograph requests" note, but I tried again three months later, this time sending a copy of a charcoal drawing of Darth Vader. I got my photos sent back with a signed yellow card. It seemed at first that I had caught him at the right time, but it appears now that sending a piece of art or something that took you a bit of time can help you get a response. If you have a drawing or some work or art of yours of Darth Vader, send it! Wait a couple of months, and you might get a response.
Billy Dee Williams (Lando Calrissian): Like with Peter Mayhew, you can buy an autograph on his website. You will receive a sorry-we-don't-send-autographs note or nothing from the address in the database.
Daisy Ridley (Rey): It's said she doesn't do autographs through the mail anymore, but she may respond vv. Try when you can.
John Boyega (Finn): He is a really nice, yet busy, guy. If you catch him at the right time using a vv address, you may get his autograph!
Oscar Isaac (Poe Dameron): He's real nice with autographs. You may get one from him if you don't send a request while everyone else is (like after a Star Wars movie is released). He takes about eight months and with personalize it or write the name of the character.
Andy Serkis (Snoke): If you send the proper postage to the address in the database, he'll likely respond.
Domhnall Gleeson (General Hux): He still responds, but it may take a while, for he's given batches of letters together; he doesn't respond one letter at a time. Don't send a picture of General Hux, but one of him as William Weasley from Harry Potter or just himself. If you don't know Irish postage, don't stamp the envelope and just send a SAE. The secretary or autograph manager is nice and will take care of the postage. Autographs may slow down around the time a new Star Wars movie come out. Try him now (this post edited on 5/26/17) or a year after The Last Jedi.
Adam Driver (Kylo Ren): He's hard to get, maybe harder than Ben Mendelsohn. There have been no successes using the address on this website, nor a vv address success.
Conclusion: Try Mark Hamill, James Earl Jones, Andy Serkis, Samuel Jackson, and Oscar Isaac. Felecity Jones may sign again with Rogue One has died down, as well as Domhnall Gleeson after The Last Jedi. Try Daisy Ridley, Adam Driver, Oscar Isaac, and John Boyega vv. If you would like a pre-print, try Ewan McGregor and Harrison Ford. If you're willing to spend a good amount of money, sign up on a different website and get the rest's addresses there. Don't waste your postage on Natalie Portman.
