Assassin's Creed Movie - 1st trailer out

Jeremy Iron as Abstergo Leader (Alan Rikkin)? This is an amazing choice dude.. He was great as Rodrigo Borgia in Borgias TV Series.. Assassin's Creed is one of the my favourite game alongside Mortal Kombat, Resident Evil, Diablo and Silent Hill. Very nice to see a cast which is contains Jeremy Irons, Marion Cotillard and Michael Fassbender (he was great as Macbeth), but who the hell is these movie characters; Aguilar, Dr. Sopphia Rikkin etc? Where is Desmond Miles? Also i have heard a rumour that we will see %65 present world and %35 past.. It will be a little bit dissapointing for me if it happens..
