...are you familiar with this upcoming Sideshow Collectibles version of Obi-Wan Kenobi?
It's a special release that bridges the 20-year gap between REVENGE OF THE SITH and A NEW HOPE by showing Obi-Wan gradually aging from Ewan McGregor to Alec Guinness. I think it will have two different heads that are interchangeable, one with an older-looking McGregor face where he's starting to wrinkle and get gray hairs(see above) and a second with a younger-looking Guinness face to represent Obi-Wan's slow morph from one actor into the other during his long exile on Tatooine. It's the only collectible that's ever tried to bridge the visual gap between Ewan and Alec by depicting at least part of the character's aging and transition. Whaddya think, man? Pretty cool!
