"Roswell" cutie Katherine Heigl has signed on to play a pre-med student in the Warner Bros' flick "Valentine."

Heigl will join fellow WB star David Boreanaz in the film that is based on Tom Savage’s 1996 book "Valentine: A Novel". Boreanaz plays a college nerd who becomes the victim of a cruel practical joke by four women. Over a decade later, he has become suave, handsome and successful, yet still carries a grudge. He kills three of the four women on successive Valentine’s Days, leaving one more to slay in order to complete his vengeance.

Filming began in mid-July for the film's Valentine Day release in 2001.

Heigl can next be seen on the big screen in the upcoming teen comedy "100 Girls", and stars as the lone female alien in The WB's Monday night program "Roswell."
