For those who love the Gamera trilogy, youtube member Onyasai21 has uploaded Japanese unsubtitled television specials for each film in parts complete with the commercials they were shown with (David Copperfield is among those advertised). Here is my analysis of the special for "Gamera: Guardian of the Universe" which I wrote on Kaiju Galaxy forums:
"And I got to say, the TV special - which I also found ones for G2 and G3 - already on their respective discs - is very revealing. First, it is interesting to see how G1 was promoted just as Gamera's return, while the second film was promoted as the tour de force of the Japanese SFX film, and the third film was like a Japanese "Tranformers".
To be more specific, it is interesting in the little details these things old. For the TV special for GGOTU, you see stuff like the inside of Daiei's production studios (decorated in GGOTU memorabilia), a figure contest for a Marmit figure (they film the winner and a kid crying because he lost), and extra footage from the Yabari International Fantastic Adventure Film Festival. Wanna know something which the ADV disc left out in that footage at the film festival? Acclaimed actress Michelle Yeoh saying how much she liked the film's SFX and how she wished that films made in Hong Kong can reach the same level of technical excellence. Mind blowing stuff in these things!"
