Worth Watching: Megan Thee Stallion Co-Hosts ‘Tonight,’ ‘Alone’ Gets Frozen, Baseball in the Field of Dreams

11:35/10:35c

Fresh and familiar faces have been keeping things interesting in late night during summer’s dog days. Joe Walsh is the latest music legend to sit in for a week’s residency on The Late Show with Stephen Colbert, ABC’s Jimmy Kimmel Live! has been welcoming guest hosts all summer—David Alan Grier is scheduled to fill in tonight—and working alongside Jimmy Fallon for a one-night stand as co-host is superstar rapper Megan Thee Stallion. Having just made a splash as Tina Snow on the Starz drama P-Valley, she’ll help deliver the monologue with Fallon and interview guests including Stranger Things’ Natalia Dyer. Hard to imagine she won’t also groove with The Roots before the night is over.

Until she went into labor at school, not even knowing she was expecting, overachieving high-schooler Olympia Chalmers-Davis (a soulful Nathalie Morris) thought her upcoming presentation in class was her biggest headache. Shock becomes denial—“Get that thing away from me,” she growls at the nurse bringing her newborn for inspection—in a sensitive Australian dramedy that explores the impact of this surprise arrival on Oly’s family, including her currently estranged parents, and that of Santiago (Carlos Sanson Jr.), the student athlete whose identity Oly is keeping secret. For now. The half-hour series opens with back-to-back episodes.

Raising the stakes, and possibly a few chilblains, the Alone franchise pushes the misery envelope in an icy spinoff. Six former participants—survivalists Greg Ovens (season 3), Woniya Thibeault (season 6), Michelle Finn (season 8), and from season 7, Callie Russell, Mark D’Ambrosio and Amós Rodriguez—are stranded with few supplies off the North Atlantic Coast of Labrador, Canada as winter sets in. Frigid conditions including incessant rain and fierce winds, plus a dense population of polar bears, make this version of Alone allegedly the most extreme to date. Those who stick it out for 50 days will share a $500,000 cash prize. For us at home, this might at least take our minds off the latest heat wave.

Baseball and movie fans got chills of sentimental nostalgia a year ago when the White Sox and Yankees met on the iconic Iowa ballpark immortalized in the 1989 movie Field of Dreams, with players in vintage uniforms emerging from the cornfield to play ball. When they played it, we came to watch—drawing robust enough ratings to merit a sequel, pitting two teams from the Midwest: the Cincinnati Reds (which I grew up cheering in their Big Red Machine 1970s heyday) and the Chicago Cubs. Players will again be decked out in uniforms reflecting the early 1900s, and viewers will be plugged into the action with Reds first baseman Joey Votto and Cubs outfielder Ian Happ wearing mics to interact with broadcasters Joe Davis and John Smoltz between plays. (Expect a tribute to the late Dreams star Ray Liotta.)

Having lived for years with someone who’s lactose intolerant, I can appreciate a food competition for folks with tricky dietary restrictions. Vegan foodie host Tabitha Brown recruits a revolving panel of judges (with Maneet Chauhan the mainstay) to sample cuisine from four chefs who each week take on challenges like Southern food with only plant-based ingredients or a gluten-free noodle dish or a dinner party minus fruits and veggies. Home cooks might even learn some new tricks along the way.
