The moment Mike Myers needs the money we can move forward with my Austin Powers vs the Evil Dead movie that exists solely so Austin and Ash can say "Groovy" back and forth at each other.
Eventually Ash says "Shagadelic" while pumping a shotgun. This is the emotional climax of the movie.
Post credits we tease Mike Myers vs Michael Myers from Halloween. We absolutely do not follow through with that tease in another movie.
Observation: Every Walter White impression starts with “Jesse” every Frank Reynolds impression starts with “Charlie” and every Shrek impression starts with “Donkey”
"The costumes [in Austin Powers] are very much inspired by the British music scene. A lot of Austin came from George Harrison, combined with a little Mick Jagger." - Deena Appel, LA Times (June 1999)
Q: Were there any musical influences from the 60s that inspired the designs?
Deena Appel: A lot of Austin is not just film, but George Harrison was a big influence for me. I was looking at The Beatles and their transformation and just what a dandy George Harrison was specifically. And so there are very specific references to his style as well.
