Six actors, Sean Connery, George Lazenby, Roger Moore, Timothy Dalton, Pierce Brosnan, and Daniel Craig, have portrayed James Bond in feature films (David Niven also played Bond in Casino Royale in 1967, but many consider that film "unofficial").
Redditor g_noodle combined Bond portraits of the six actors into two "transition" Bonds, with the three "early" Bonds (Connery, Moore, Lazenby) on the left and the three "recent" Bonds (Dalton, Brosnan, and Craig) on the right. Then those two images were combined to achieve a final combination, which looks like an actor who would be considered perfect for the role.
Who does it look like to you? Clive Owen? George Clooney? Mel Gibson? I still see Sean Connery and Roger Moore in this picture. The various steps in the process are shown in a series at imgur. Link -via reddit
