A scene from "Animals"

Dog days of summer: Summer is really going to the dogs. HBO's "Animals," the laugh-out-loud animated series that's definitely not for children, returns for a third season on Friday, Aug. 3, with tons of new guest stars, but also its hilarious approach to comedy that blends its distinct style of animation with live action.

The show, which is heavily improvised by its actors, features a broad cast of animals living in New York City, including rats, flies, squirrels, pigeons, dogs and cats. Voiced by show creators Phil Matarese and Mike Luciano, the cartoon creatures interact with each other and with live-action humans, with each season featuring a surprisingly tight plot, considering how off the cuff much of the dialogue can be.

With the Big Apple's humans wiped out by the events of season 2, it's time for the animals to take over -- and plenty of those animals are voiced by this season's guest stars. Sharp-eared viewers can catch the voices of former "Saturday Night Live" writer John Mulaney ("Mulaney"), Tracy Morgan ("30 Rock"), Natasha Lyonne ("Orange Is the New Black"), Lucy Liu ("Elementary"), Demi Moore ("G.I. Jane," 1997), Edie Falco ("The Sopranos"), Michael Sheen ("Masters of Sex") and rapper Awkwafina ("Ocean's Eight," 2018), to name just a few.

While "Animals" is definitely about the city's furry (feathered, multilegged, etc.) creatures, each season also features a humancentric plot arc that ties everything together. In the first season, a corrupt mayor was running for re-election, while season 2 featured a virus outbreak in the city and followed a reporter investigating its causes. 

They call this time of year the dog days of summer, but on HBO, it isn't just dogs getting a place in the spotlight. The third season of "Animals" premieres Friday, Aug. 3.

Back on screen: Grace Park is returning to the small screen. The former "Hawaii Five-0" star has joined the cast of an upcoming ABC drama, just a year after she and "Five-0" co-star Daniel Dae Kim left that procedural.

Park joins "A Million Little Things" not long after its pickup to series following a successful pilot. She'll be playing working mother Katherine, a role that was played by Anne Son ("NCIS: Los Angeles") in the pilot.

"A Million Little Things," which is expected to air Wednesdays on ABC once the fall TV season gets underway, is a drama about a group of longtime friends who all find themselves receiving a wake-up call when one of them suddenly dies. It's been compared to NBC's runaway hit "This Is Us," and if "A Million Little Things" can nail even a hint of that show's success, then it will be in a very good place.

Park joins a talented and diverse ensemble cast that includes Romany Malco ("Weeds"), Ron Livingston ("The Conjuring," 2013), Allison Miller ("13 Reasons Why"), James Roday ("Psych"), Christina Ochoa ("Animal Kingdom"), Christina Marie Moses ("The Originals"), Stephanie Szostak ("Dinner for Schmucks," 2010) and Lizzy Greene ("Nicky, Ricky, Dicky & Dawn"). 

Park earned the loyalty of countless fans during her seven-season stint in "Hawaii Five-0," and now she's finally returning to a regular prime-time role. "A Million Little Things" premieres this fall on ABC.

Alien history: Syfy's "Krypton" has been renewed for a second season, but that's no surprise: the first season was the biggest hit the specialty channel has had in a while.

The series stars Cameron Cuffe ("The Halcyon") as Superman's grandfather Seg-El living on the planet Krypton as a young man, years before its destruction. It had the most-watched first season for an original series on the network, since "Ascension" premiered in 2014, and it brought in the highest viewership for any scripted series on the channel since 2015.

Those are some impressive numbers for a show that isn't even about the popular superhero, but rather his not-so-super ancestor. "Krypton" lays the foundation for the political events that will eventually, decades in the future, lead to that world's destruction, and the infant Superman being sent to Earth.

Of course, Seg-El doesn't live in a vacuum, and "Krypton's" diverse cast brings the alien civilization to life. Georgina Campbell ("Black Mirror"), Elliot Cowan ("The Golden Compass," 2007), Ann Ogbomo ("Wonder Woman," 2017), Aaron Pierre ("Britannia"), Rasmus Hardiker ("Lead Balloon"), Ian McElhinney ("Game of Thrones") and Blake Ritson ("Da Vinci's Demons") all play an array of Kryptonians, while Shaun Sipos ("Final Destination 2," 2003) plays a human who has come from the future with a warning about what's to come.

"Krypton's" first season was a huge hit, so it's no surprise that a second one is in the works. It's expected to premiere sometime in 2019 on Syfy.
