There is a scene I remember from a film, and I want to see the whole 
thing. 
  
The scene started with the star of the film practicing Tai Chi, or 
some other type of martial art, in the park. 
  
On the bench were a couple of bums watching. After a while one of the 
bums starts joining in. 
  
Then they show the guy practicing a few days later, and about a dozen 
bums are practicing with him. 

What is the name of this film?
