Katherine in Denver, Filming Reading PSA

From the Denver, Colorado “Rocky Mountain News”:

ALIEN SPOTTED IN LIBRARY: Katherine Heigl, who plays alien Isabel Evans in the WB TV show Roswell, landed in the Denver Public Library Wednesday to shoot a public service announcement for the library’s “Teen Summer of Reading” program, which will air in June.

“A woman who plays an alien seems like a perfect match for people who sometimes feel like aliens,” said library spokeswoman Anya Breitenbach.
