The fourth season of Room 104 premieres on HBO July 24. The series, from Mark and Jay Duplass, looks at a single room at a hotel, and all the funky stuff that happens in the room over time. HBO announced it is the final season, and the producers are keen to keep it going. 

“We hear, you’ve done 48 episodes inside those four walls--that’s enough,” said Mark, an executive producer. “The truth is, we have more ideas. We hope somehow, somewhere, there’s a new version of this show.”

Room 104 could take on another format, he added, such as a podcast. 

Exec producer Mel Eslyn said Room 104 has “limitless possibilities.”

“We would love to do season five, six, seven,” she said. 

But for now, it’s just season four. 

Kicking off the season, Mark Duplass will watch seasons one, two and three July 24, live tweeting all the while from @MarkDuplass. HBO is calling it “Open the Door to @MarkDuplass’ Mind.”

Eslyn said they formalized the writers’ room more for season four than they had in previous years. That would see the producers in a room together more than in seasons past, brainstorming ideas. “We’d talk about what was left inside of us, what we hadn’t explored in that room,” she said. 

The first episode, called The Murderer, is a fun one. A group of friends that are obsessed with this singer-songwriter who disappeared off the face of the earth after putting out an album as a teen finds the guy and gets him to perform in room 104. “I’m obsessed by what it means to be a fan,” said Mark, noting how music zealots tend to “take great joy out of pain” when listening to their favorite artists. 

Mark Duplass approached his friend Mark Kozelek, who has sung for Sun Kil Moon and Red House Painters, about playing the part of long-lost singer Graham. Kozelek turned it down, so Duplass, who has a musical background, took it on himself. He loved the idea of a mythologized, super-cool artist turning up in modern day, looking like a “sad uncle” in cargo shorts and cheesy golf shirt.

Eslyn loves the episode called “The Last Man”. “It pushes the boundaries of staying in the room more than the others,” she said. “And we got to have a swordfight!”

Exec producer Sydney Fleischmann directed her first episode, the season finale titled “Generations”. It’s about an older man reflecting on his life. Fleischmann envisioned her two 92-year-old grandfathers as the episode came together. “They’re in the winter of their lives, assessing the lives they’ve lived,” she said. 

Mark Duplass mentioned the “conscious uncoupling” of he and brother Jay over the course of the series, as the longtime partners pushed each other to find unique voices to take part in the series, and share the storytelling load. “It energized me, and it kept the show from becoming repetitive,” he said. 

Jay of course played Josh Pfefferman on Transparent. 

Asked for his favorite Room 104 episode, Mark mentioned a musical one, entitled “Arnold”, from season two. The episodes that took big risks, he said, ended up among his favorites. “That one not only didn’t fall on its face, but was one of our more creative and most successful episodes,” he said. 

Eslyn said Room 104 “took a lot of storytelling risks” over the course of its run. 

As they prepare to sign off, Eslyn will miss getting photos of friends in front of various hotels’ room 104s. Working on the show has changed her relationships with hotels. 

“I always think something’s up in the bathroom,” she said. “And I definitely look under the bed.”

A number of new and returning reality-themed series highlight this week's lineup of new and returning cable network and streaming service shows.

National Geographic this week fully dives into its eighth-annual SharkFest programming stunt that will run over the next five weeks, according to network officials.

Other reality-themed shows include the July 23 debut of TBS's The Lost Resort and the July 22 premiere of Netflix's Love on the Spectrum. 

On the scripted front, HBO on July 24 will debut the fourth and final season of its drama anthology series Room 104.

Below are video trailers and premiere dates for several other shows debuting the week of July 20 to July 26 on cable networks and streaming services (for some videos, viewer discretion is advised):

July 21 -- Street Food: Latin America (reality) -- Netflix

July 22 -- Corporate (comedy) -- Comedy Central

July 23 -- The Dog House (reality) -- HBO Max

July 23 -- Tig n’ seek (animation) -- HBO Max

July 24 -- Radioactive (drama) -- Prime Video

July 24 -- Raven About Bunk’d (special) -- Disney Channel

July 25 -- Surviving Joe Exotic (reality) -- Animal Planet

July 26 -- Wynonna Earp (returning series) -- Syfy 

The fourth and final season of Room 104 starts on HBO July 24. The 12 episodes tell “a unique and unexpected tale of the characters who pass through a single room of a typical American chain motel,” according to HBO. 

Mark and Jay Duplass created the show. Executive producer Sydney Fleischmann said the ethos of the series has always been “creating rules, then we break them. This season, we really put the rules to the test.”

The premiere episode is a funky one. A group of friends adores a teen songwriter who disappeared decades before. One of them finds the man, and gets him to perform for the small group in, yes, room 104.

Mark Duplass spoke with a musician or two about playing the character, and finally took on the role himself. He sings and plays a distinctive guitar. “We wanted a guitar that was well-loved and well-used,” Fleischmann said. “This guitar has been around the block.”

Fleischmann directed her first episode, called “Generations.” It is the series finale and shows an old man reflecting on his life. Fleischmann’s 92-year-old grandfathers, “in the winter of their lives,” were an inspiration, she said. 

She said Room 104 doesn’t feel over. “It really feels limitless,” she noted. “We feel like we can keep going.” 

Movie Upside-Down Magic premieres on Disney Channel July 31. Izabela Rose plays Nory Boxwood Horace, a student at the Sage Academy for Magical Studies. While at Sage, she’s quickly shoved into a class for those with upside-down magic — those whose powers don’t quite work the way they’re supposed to. 

Nory’s a tough kid. “She has so much energy and enthusiasm and excitement for the world, and for everybody around her,” said Joe Nussbaum, director/exec producer. “It takes a lot to put her down. It takes a lot to crush her spirit.”

The movie is based on a book of the same name. Nussbaum got a look at the script and was hooked. “I loved the concept,” he said. “I loved the idea.”

Nory’s powers are considered “wonky,” in Upside-Down Magic verbiage. She at times turns herself into a “dritten” — half dragon, half kitten. 

Upside-Down Magic may put one in mind of another book series/film franchise about a child at a school for kids with magical powers, but Nussbaum said the Harry Potter overlap is minimal. It’s similar “insomuch as it’s a school for magical kids,” he said. “Hopefully it has a different look and a different feel.”

Nussbaum suspects the timing is right for the film premiere. “We could all use a little escapism in 2020,” he said. “We could all use a story of good versus evil.”
