It's not just movie trailers that have teasers these days. Right now you can watch a teaser clip for Samsung's superbowl ad directed by Jon Favreau of Iron Man fame and starring Seth Rogen and Paul Rudd.
You may or may not know that the term "Superbowl" is actually trademarked and copyrighted in the same way "the Olympic Games" is. That means that someone could actually be taken to court for saying it in connection with their product. This makes it particularly hard for Samsung, who has just put out its ad for "the big game".
It does a good job of mentioning the big game, but I'll be damned if I know what Seth Rogan and Paul Rudd are on about.
I prefer playing a little game called spot the celebrity in Samsung's last Superbowl ad.
