A British comedy reunion, a new Netflix anthology date and a significant Grey’s Anatomy casting move lead this week’s verified entertainment briefing. The integrated Sci-Fi, Fantasy & Horror section then ranks four important developments announced, reported or activated between 3 and 9 September 2026, with audience impact and the strength of the underlying confirmation guiding the order.
Headline News
The Inbetweeners 3
- Status: Production began in the UK on 7 September 2026
- Format: Netflix feature film
- Writers and directors: Damon Beesley and Iain Morris
- Returning cast: Simon Bird, James Buckley, Blake Harrison and Joe Thomas
- Release date: To be announced
Netflix has started UK production on The Inbetweeners 3, continuing the original sitcom and its two feature films. Simon Bird, James Buckley, Blake Harrison and Joe Thomas are all returning, while series creators Damon Beesley and Iain Morris will write and direct.
Why it matters: This is a production-start confirmation rather than another development rumour: the core quartet and the original creative partnership are now working on a Netflix feature. Viewers still need to wait for a release date.
Lust Stories 3
- Streaming: 18 September 2026 on Netflix
- Format: Four-story Indian anthology film
- Directors: Vikramaditya Motwane, Kiran Rao, Shakun Batra and Vishal Bhardwaj
- Cast includes: Radhika Apte, Konkona Sen Sharma, Aditi Rao Hydari and Vijay Varma
- Availability: Global Netflix release
Netflix has set Lust Stories 3 for 18 September. Its four new stories come from Vikramaditya Motwane, Kiran Rao, Shakun Batra and Vishal Bhardwaj, with an ensemble spanning Radhika Apte, Konkona Sen Sharma, Aditi Rao Hydari, Vijay Varma and others.
Practical impact: The announcement gives the anthology franchise a near-term global date and a complete creative line-up, making it an immediate addition to September watchlists rather than an undated project.
Grey’s Anatomy — Season 23
- New recurring cast: James Wolk as Dr Seth Norton
- Character: A medical professional turned healthcare businessman
- US return: 15 October 2026 at 10 p.m. ET on ABC
- Creator: Shonda Rhimes
- Returning lead: Ellen Pompeo
James Wolk has joined season 23 of Grey’s Anatomy in the recurring role of Dr Seth Norton. Shondaland describes Norton as a former medical professional whose luxury-care business puts the bottom line first, setting up a new source of pressure around Grey Sloan.
Why it matters: The role gives the new season a character positioned between medicine and corporate healthcare, while the announcement also confirms the US return date and time. UK availability has not yet been specified by the source.
Sci-Fi, Fantasy & Horror
1. Supergirl
- Global streaming: 10 September 2026 on HBO Max
- US television: 12 September at 8 p.m. ET on HBO
- Director: Craig Gillespie
- Starring: Milly Alcock, Matthias Schoenaerts, Eve Ridley and David Krumholtz
- Format: DC Studios feature film
Warner Bros. Discovery has confirmed that Supergirl makes its global streaming debut on HBO Max on 10 September, followed by an HBO linear premiere in the US on 12 September. Milly Alcock leads Craig Gillespie’s DC Studios film.
Why it ranks first: It is the week’s broadest near-term genre development: a major theatrical superhero release receives an exact global home-viewing date just one day after this round-up.
2. Practical Magic 2
- International cinemas: Opening from 9 September 2026
- North American cinemas: 10 September 2026
- Director: Susanne Bier
- Starring: Sandra Bullock, Nicole Kidman, Joey King, Lee Pace and Maisie Williams
- Source novel: The Book of Magic by Alice Hoffman
Practical Magic 2 begins its international cinema rollout today before opening in North America on 10 September. Sandra Bullock and Nicole Kidman return as the Owens sisters, with Susanne Bier directing from a screenplay based on Alice Hoffman’s The Book of Magic.
Why it ranks second: This is the section’s most immediate cinema event, combining a returning lead pair with a confirmed worldwide distribution plan. Exact sessions will vary by market and cinema.
3. Silo — Season 3
- Season finale: Episode 10, “Troy,” released 4 September 2026
- Streaming: Complete season available globally on Apple TV
- Creator and showrunner: Graham Yost
- Starring: Rebecca Ferguson, Common, Harriet Walter and Jessica Henwick
- Based on: Hugh Howey’s Silo novels
Silo completed its ten-episode third season on 4 September with “Troy.” The finale’s arrival means the whole season is now available on Apple TV, while the series remains renewed for a fourth and final chapter.
Why it ranks third: The development changes the practical viewing proposition: weekly viewers have reached the endpoint and newcomers can now watch the complete season. This briefing avoids finale spoilers.
4. Onslaught
- US cinema release: In cinemas from 4 September 2026
- Director: Adam Wingard
- Starring: Adria Arjona, Dan Stevens, Eric Wareheim and Rebecca Hall
- Distributor: A24
- Genre: Science-fiction action horror
Adam Wingard’s Onslaught opened in US cinemas on 4 September. Adria Arjona leads the genre film as an Army sniper protecting her daughter after genetically engineered soldiers break loose in the desert.
Why it ranks fourth: The release moves the project from advance publicity into an active theatrical run, but the verified date is US-specific and therefore narrower in practical reach than the global streaming and international cinema developments above it.
Why It Matters
This week’s strongest verified developments span the full screen pipeline: a production start with its original comedy team, a dated global anthology, a notable network-drama addition, a superhero streaming handover, an international fantasy sequel opening, a completed science-fiction season and a new US genre release. The ranking favours developments audiences can act on now and labels territorial limits clearly.
Movieversalfilm Takeaway
Supergirl is the widest immediate home-viewing development, while Practical Magic 2 is the week’s time-sensitive cinema choice. Silo is now ready for a complete-season watch, and The Inbetweeners 3 has finally crossed the line from reunion talk into production.
What to Watch Next
Watch Supergirl on HBO Max from 10 September, check local cinema listings for Practical Magic 2, or settle in for the now-complete third season of Silo on Apple TV. Lust Stories 3 follows on Netflix on 18 September.
