Q: Will the fourth season of "Snowpiercer" ever air? As I understand things, It was filmed, but TNT decided not to air it.

A: TNT carried three seasons of the post-apocalyptic drama based on the movie of the same name and ordered a fourth. The network then decided not to air the fourth season, reportedly as a tax write-off. AMC has finally come to "Snowpiercer's" rescue, acquiring all four seasons. The first three seasons will stream on AMC+ later this year, and the previously unseen fourth season will be on AMC and AMC+ in 2025.

Sajak still leaving

Q: I remember last year that Pat Sajak from "Wheel of Fortune" was going to retire at the end of 2023 and Ryan Seacrest was going to replace him. I see that Sajak is still on. Did he change his mind?

A: Last year it was announced that Sajak would leave "Wheel" at the end of the current season, not the end of the calendar year. His last new telecast is scheduled for June 7. But, as a program representative noted, he'll still be seen on the show over the summer when it airs reruns.

Trading places

Q: In the early '60s there was a sitcom about two teenage girls, one British and one from America. They traded places and families. The British girl was Heather. Do you remember the name of the show, or am I just imagining it?

A: Your memory is fine. The show was "Fair Exchange," which aired on CBS from a single season in 1962-63. It involved families in New York and London who let their daughters trade places; the American daughter was played by Lynn Loring, the English one by Judy Carne. "The Complete Directory to Prime Time Network and Cable TV Shows" notes that it was at first an hourlong comedy, low-rated and canceled. Then the "unexpected volume of mail" from fans led to its return, but as a half-hour show — also low-rated, then canceled for good.

More 'Outlander'

Q: When will the rest of this season's "Outlander" happen?

A: The drama based on Diana Gabaldon's novels will begin the second half of its seventh season on Starz in November. An eighth season, which reportedly will be the last one, is in the works, along with a prequel series, "Outlander: Blood of My Blood."

'All Rise' falls

Q: Are there plans for another season of "All Rise"? There didn't seem to be closure for the characters and story lines at the end of the previous season.

A: The series has ended after three seasons, the first two on CBS and the last one on OWN.

Run to 'Buddy'

Q: I am writing to you about the funniest show I ever watched, "Run, Buddy, Run," with trumpet player Jack Sheldon as its star. I wonder if you can tell if any network would have reruns for me to see.

A: "Run, Buddy, Run" aired on CBS for one season in 1966-67. A comedic variation on "The Fugitive," it had Sheldon playing Buddy Overstreet, a man on the run after overhearing some gangsters' plot. I found some episodes on YouTube, with the credits in German ("Renn Buddy Renn"), but the dialogue in English.
