Well, the one that comes to mind is a oldie of sorts, from the mid to late 90s.
A Nike/Air Jordan's commercial.
Its a commercial where everything is in slow motion as Jordan drives to the hoop in the darkened arena (I think) while the action cuts to people watching jordan on TV also moving in slow motion. All while some orchestrated music is playing.
Anyone remember this? If so and you know how to find it, I would LOVE to see it again. That is the first commercial that comes to mind.
Just watched the Big Ad for the first time and it's incredible! Brilliant stuff. The 250,000 bouncy balls was beautiful to watch and the song is my new favorite. There was a commerical about 10 years ago for Shren fishing line. It had an children's amateur stage production (at school). There was a fairy princess hovering over the stage and right in the middle of her dialogue her strings broke an she fell right to the stage. SMACK! Then the words came up, "Should have used Shren." Very clever.
