A Norwegian film with most of the dialogue in English (along with English subtitles), Mortal is a fantasy action movie inspired by Norse mythology with sci-fi elements integrated into the plot. Eric (Nat Wolff) wakes up in the wilderness to discover that he not only has terrible burns but that virtually everyone he touches dies. He meets with a psychologist named Christine (Iben Akerlie), who tries to help after discovering his powers are controlled by his emotions.
Mortal was well received by viewers and earned mixed reviews from critics. Jared Mobarek of The Film Stage calls the movie a “fascinating take … with some cool set pieces and a willingness to increase stakes by killing characters and dealing with the complexity of the aftermath.”

Sirona (Ashlynn Hideman) is a young woman with supernatural gifts. She escapes from a government facility where she is being held captive and people are conducting experiments on her. But her freedom is short-lived because soon, she finds herself on the run from mercenaries who are desperate to capture her and take her back.
Earning a 90% Rotten Tomatoes audience score, Sirona is one of those lesser-known indie films for fans who revel in finding underground gems. But views are polarizing, and Sirona will only appeal to those who appreciate low-budget sci-fi and all of its charms.

Based on the Marlen Haushofer novel Die Wand, The Wall is an Austrian-German sci-fi drama about Die Frau (Martina Gedeck), who travels to a remote hunting lodge with friends only to realize that after they go out for a walk, she is trapped behind an invisible wall. She spends three years alone with the help of her friend’s dog, struggling with isolation, depression, and confusion as to what is going on.
Earning decent reviews, The Wall is a heavy, haunting movie that’s not your traditional sci-fi. Boston Globe’s Ethan Gilsdorf describes The Wall as “bleak and beautiful, harrowing yet inspiring … a stunning tale of isolation and survival in a wild and silent world.”

Some of the best shots in Grok Imagine’s AI-made Odyssey don’t contain actors. Ancient landscapes stretch into the distance. Close-ups of grimy hands suggest people who have touched something rougher than a keyboard. For a few seconds, the illusion holds.

YouTube videos could soon look better without eating quite so much data, right? Thankfully, the platform plans to introduce a new video format called AV2 on its web player in early 2027, promising more efficient streaming and potentially fewer playback hiccups on slower internet connections. The big headline is a roughly 30% improvement in compression efficiency over AV1, YouTube's existing video format. That doesn't guarantee every video will use 30% less data, but it could make streaming a little easier on both internet connections and data allowances.
What is AV2, and why should viewers care?
YouTube is changing how its Home page works, giving viewers more control over what shows up there and making some of the app’s most-used sections easier to reach. Custom Feeds are now replacing the existing topic chips for eligible users, while YouTube is also testing a redesigned top bar on mobile that moves Subscriptions closer to the Home feed.
YouTube first started experimenting with Custom Feeds earlier this year, letting you type out what you wanted to watch and turning that request into its own stream of recommendations. Now, the feature is starting to look less like a side experiment and more like something YouTube actually wants people to use as part of their everyday Home page.
