In the new made-for-TV “Summer of Dreams” (Hallmark, 9 p.m.), Debbie Gibson plays a part that’s not too much of a stretch — an 80s pop star whose career is in decline. While for the real Gibson, this may mean performing in a Hallmark movie, for the character, it means becoming a music sub at a school in Ohio. Because it’s Debbie Gibson, she sings “Only In My Dreams.” Because it’s Hallmark, romance is involved.
On the made for TV “Unwanted Guest” (Lifetime, 8 p.m.), a college student invites a weird friend to stay with her family. Ted King, Kate Mansi and Beth Littleford star.
It’s never a good sign when a series moves to Saturday night, as it has for “Aquarius” (NBC, 9 p.m.), the David Duchovny police period piece in its second season. Both episodes are named after Beatles songs: “While My Guitar Gently Weeps” at 9 and “Sexy Sadie” at 10.
Primetime preseason football has Tennessee at Oakland (CBS, 8 p.m.).

It’s the case of the killer cougars on “Deadly Women” (ID, 10 p.m.).
The Pamela Smart case is dug up on “Murder Made Me Famous” (Reelz, 9 p.m.).
“The Naked Gun” (IFC, 8 p.m.) and “The Naked Gun 2 1/2” (IFC, 10 p.m.) still hold up, if not for Leslie Nielsen and Priscilla Presley, at least for O.J. Simpson.
Those who hated the recent “Ghostbusters” may want to check out the more inferior “Ghostbusters II” (VH1, 8:30 p.m.), which follows the original “Ghostbusters” (VH1, 6 p.m.).
“The Mummy” (AMC, 7 p.m.) paired with “The Mummy Returns” (AMC, 10 p.m.) means: too much Brendan Fraser.
So many double features! There is also “City Slickers” (Pop, 6:30 p.m. and “City Slickers II: The Legend of Curly’s Gold” (Pop, 9:30 p.m.).
“Flex & Shanice” (OWN, 9 p.m.) take a belated honeymoon in Hawaii.
Ginger Spice of the Spice Girls and Ed Lover of “Yo! MTV Raps” are tracked down for a new edition of “Oprah: Where Are They Now?” (OWN, 10 p.m.). But the real attraction may be two surviving cast members of “Family Affairs” — Kathy Garver, now 70, who played Cissy, and Johnny Whitaker, Jody himself, who is now 59.
Not surprising that Fox News gives a Saturday night showcase to the already much-repeated exercise in posterior kissing, “Hannity: Trump Town Hall” (Fox News, 8 p.m.). Watch those marshmallows!

Baseball includes Minnesota at Toronto (MLB, 1 p.m.), Cubs at Dodgers (Fox Sports 1, 4 p.m.), Angels at Detroit (Fox Sports 1, 7 p.m.) and Atlanta at San Francisco (MLB, 10 p.m.).
There is one weird college football game before the impending deluge. It’s Charleston Southern at North Dakota State (ESPN, 7:30 p.m.). Sure beats high school football (ESPN2, 6 and 9 p.m.;ESPNU, 8 p.m.).
Kacey Musgraves and Dale Watson play a replay of “Austin City Limits” (PBS, 11 p.m.) from 2014.
