Wild about Harry

"Harry Styles at the BBC" may be designed for hysterical One Direction fans, but grownups will warm to this multifaceted entertainer with his visit to a Manchester nursing home and a rendition of Fleetwood Mac's "The Chain." Quite a charmer, this one.

Bachelorette party

The royal wedding is still a few weeks away, but you can get the festivities started with "Meghan Markle: American Princess," one of a slew of documentaries on the bride-to-be that coincides nicely with the actress' sendoff on Wednesday's season finale of "Suits."

Designing woman

Minnesota native Genevieve Gorder finally makes her appearance on the reboot of "Trading Spaces," just in time to help a son and his parents screw up each other's master bedrooms. Even without Gorder around, the series was doing well, giving TLC its best Saturday-night numbers in eight years.

Way out west

If your head has finally stopped reeling from all the twists, turns and time jumps in Season 1 of "Westworld," you might just be ready for new episodes. They're far less confusing but equally as grim, with "the hosts" running amok on an even bloodier, more violent battlefield. Oh, Shogun World is open for business. Enter at your own peril.

8 p.m. Sunday, HBO
