It’s a little difficult to tell the good guys from the bad guys on USA’s “Burn Notice,” and that’s one of the things that make the character-driven thriller unique.

When star Jeffrey Donovan was cast as the spy who is driven in from the cold, he knew a lot about Bruce Campbell, who was to play his unkempt cohort, Sam.

“I knew of Bruce,” says Donovan. “I actually had heard about him through a friend of mine who knew him. So I knew just of him, but that’s not to say that I wasn’t a fan of his because I don’t actually know many actors – because I don’t go to the movies and I don’t watch television. But now that I’ve gotten to know him, I couldn’t ask for a better costar. And I’m sure actors say that all the time, but they’re lying. I know all of them. They’re lying. And this is the truth. You can’t ask for a better actor coming from his huge career, to come and grace us on this show has been just a blessing for us.”

The Crossing Jordan episode that Jeffrey guest starred in aired last night and you can view the screen captures and/or watch a video clip from the episode.

The powerful drama Crossing Jordan (Sundays, 10-11 p.m. ET, beginning January 21) from NBCs Heroes executive producer Tim Kring heads into its sixth season and continues to explore disturbing topical crimes, while following a cadre of coroners who use their forensic skills to help the Boston police department bring murderers to justice and closure to victims families.

Jill Hennessy (NBCs Law & Order) stars as Dr. Jordan Cavanaugh, a sexy, smart and fearless medical examiner with a checkered past. She works under the guidance of Dr. Garrett Macy (Miguel Ferrer, Traffic), the no-nonsense head of the morgue, and alongside Detective Woodrow Woody Hoyt (Jerry OConnell, Jerry Maguire), who puts in the legwork to hunt down the perpetrators of crimes. Yet, Jordans unorthodox methods constantly test her professional and personal relationships.

Additional support for the investigative team is provided by grief counselor Lily Lebowski (Kathryn Hahn, How to Lose a Guy in 10 Days), forensic entomologist Bug (Ravi Kapoor, Gideons Crossing) and criminalist Nigel Townsend (Steve Valentine, The Muse). This season, trouble is in store for Jordan and her colleagues when Special Prosecutor William Ivers (Jeffrey Donovan, Touching Evil) is appointed to investigate the morgue; and Kate Switzer (Brooke Smith, Silence of the Lambs), a prickly medical examiner, joins the coroners office.

Crossing Jordan is from Tailwind Productions in association with NBC Universal Television Studio. Kring (Heroes) is creator and executive producer; Dennis Hammer (Heroes), Allan Arkush (“Heroes), Jon Cowan (“American Dreams”), Robert Rovner (“American Dreams”) and Kathy McCormick (NBC’s “Law & Order”) are executive producers.
