The 1950 logo @9:15 shocked me. The Universal globe logo with the golden glow around it that was used in the 90's now seems like a nod to their Japanese counterpart.
They even steal the clock tower theme from London Films (7:36), the same studio that brought you “Things To Come”. My guess that this was the first time that a Japanese studio uses stolen content from London Films.
My favorite was the unused one, you: *announces unused logo* me: oh boy! I like unused stuff! It makes sense that there's an unused logo, they have been here for 100 years! *Sees logo and discovers that they made the same mestake as Medusa with the last logo you showed on that video* me again: *breathes in* AAAAAAAAAAAAHHH!
You missed some varients. One for the 1956-1980 logo to which there is an English translated version ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oEiPh8lfpcw.html And one for the 1980-1993(or 1993-2003) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nQqUPJK4Je4.html (Its at 7:03 in this link)
