Frank Oz was interviewed for the LA Times.  He had some comments about Matthew Macfadyen again.
	
	American audiences might recognize Matthew Macfadyen from "Pride &
	Prejudice" (he played Mr. Darcy) and Peter Dinklage from "The Station
	Agent." But that's about it. No baggage, no egos.
	
	
	It's telling that Macfadyen, who was something of a stallion in "Pride
	& Prejudice," is doughy and spineless here. His performance is
	utterly naturalistic,...
	
	
	"What I love about Matthew and all of the other actors is that I don't
	see the sweat," Oz says. "I hate seeing the sweat on the screen. I
	don't want to see them working at comedy. I want them to be innately
	trusting of the material."
