I have uploaded scans of the ENGLISH version of the FMA: Sacred Star of Milos movie guidebook. It includes a summary of the plot, characters, and setting description, as well as various interviews with people of import and cast details. Some spoilers, but only of the "this is the premise without giving away the action" sort. Even if you’re not super interested in the movie itself, there are some worldbuilding tidbits (such as about the structure of the Amestrian government and some details about Creta) that do make browsing through it worthwhile. Also, it includes a short interview with Arakawa. It’s not much, but I found it useful!
I've also scanned and uploaded some FMA soft-folders I received, including images of Roy, Riza, the team, and Olivier.
