The Ontario Science Centre opened on September 26, 1969. In 1971 I made my first visit there as part of a school trip. The architecture and layout of the buildings, all interconnected by bridges and tunnels (containing escalators), made an impression on me. The exhibits, some of which exhibited and explained the explosion of technology, were equally memorable -- I remember playing with and being thrilled by the portable electronic calculator (which was secured to a table).
One of my strongest memories of the day concerns a certain motion picture which played in rotation at the museum's movie theatre. My dad played the role of a chaperone on that school trip, and he asked me if I wanted to see the flick as advertised by the one-sheet (showbill). I recognized which picture this was as I had seen it on German and French television a few times when we lived in (then) West Germany: The Fabulous World of Jules Verne (Original Czech: Vynález zkázy). I was enthralled and charmed.
On this side of the pond we got the slightly-Americanized version; complete with an unnecessary introduction by Hugh Downs. Almost certainly the print shown on my German-made telly was a dubbed version of the original Czech.
Interesting note: Pauline Kael, the Pauline Kael, liked Karel Zeman's The Fabulous World of Jules Verne. That's a seal of approval. (Ms Kael was second only to Leslie Halliwell in not liking a given film -- it would seem to me at times.)
I visited the Ontario Science Centre again in September of 1984 and noticed the differences right away -- technology.
Time to revisit....
