Stirring the pot

Nicollette Sheridan, possibly still reeling from her character’s death on “Desperate Housewives,” returns to the small screen as Alexis Carrington in the reboot of “Dynasty.” The hope is that the actress can bring the same kind of cattiness Joan Collins brought to the role when she joined the original series in its second season. Sheridan only pops up near the end of this week’s episode, but is front and center starting March 30.

Best of friends

Tiffani Thiessen may be playing one of the moms in “Alexa & Katie,” but the show’s title stars are wisely taking their cues from “I Love Lucy” instead of “Saved By the Bell.” Paris Berelc and Isabel May consistently generate laughs out of this nimble teen-oriented sitcom, even when the plot deals with one character’s cancer battle.

Isn’t it rich?

The kidnapping of J. Paul Getty’s grandson, which was the subject of the recent film “All the Money in the World,” gets the small-screen treatment in “Trust,” a new series from the inventive mind of Oscar winner Danny Boyle. The director approaches each episode like a separate movie with the common thread being a cruel and kinky Getty, played with relish by Donald Sutherland. But the real treat is Brendan Fraser, who plays an investigator borrowing a hat from McCloud and attitude from Columbo.

Stefon gets serious

Bill Hader may not have Will Farrell or Adam Sandler’s bankability on film, but he’s using his post-“SNL” days in more inventive ways. He’s the creator/star of “Barry,” a wholly original sitcom about an emotionally detached hitman who discovers his love of acting through a very un-Fonzie Henry Winkler. For an interview with Hader, see Sunday’s Variety section.
