I haven't seen the movie yet, but my nephews are familiar with it, and last night, they wanted me to show them the Easter egg in "Adventure." I was only too happy to oblige.
At the National Videogame Museum in Frisco, they have a little corner devoted to Adventure and the Easter Egg with an Atari with Adventure set up and a sign telling you the steps to find it.
It is a bit much, the action is not any different than an ADD enhanced superhero movie. A lot of things going on and no breaks to let you absorb it all.
