For what it's worth the American Film Institute lists the 100 most inspirational films of all time. I say "for what it's worth" because any list that ranks Chariots of Fire dead last in terms of inspiration is deeply flawed.
You'll have to go to the link to see the ranking but, no, there are no Jackie Chan or Steven Seagal movies on the list.
Meanwhile, Forbes has a list of the 100 most influential celebrities. If these are the people exerting the greatest influence over our culture, well, a lot of questions have just been answered. Here's the top ten:
1. Tom Cruise
2. Rolling Stones
3. Oprah Winfrey
4. U2
5. Tiger Woods
6. Steven Spielberg
7. Howard Stern
8. 50 Cent
9. Cast of The Sopranos
10. Dan Brown
Lord help us all.
