If these names can't carry a potent television audience, then we know these are wild television times.
Twenty-two years after the CBS-classic "Magnum P.I." went off the air, Selleck and his legendary 'stache are back with a hour-long drama "Blue Bloods," in which he plays a New York City police commissioner and the key figure in a three-generation family of Irish cops.
With stars such as Donnie Wahlberg and Bridget Moynahan playing parts in Selleck's crime-fighting family, expect the focus to be on character and story.
"While there is a good deal of police work on the streets of New York, the show is about how much that work affects the family," Selleck tells PopcornBiz. "I think this show is very much character-driven. That's where my appetite is."
"I don't think people get to see enough character-driven stuff on TV," he adds. "With reality shows and procedural cop shows, there isn't much of it around."
Shatner's return to situation comedy comes in the form of the quirky "$#*! My Dad Says," where he'll play the cantankerous father-figure dealing with his son, who has moved back home with him.
The show based on the famous Twitter account will allow Shatner to do what he does best -- ham it up. But it's not all joy for the consummate professional who is dealing with the ups and downs of a weekly studio audience.
"There’s maybe 400 or 500 people in the audience, and sometimes you can’t remember the words," he tells us. "When you’re in film, you say, 'What was that?' But here it’s very embarrassing."
