Exciting New Sci-Fi and Fantasy Series in May 2023

Star Wars: Visions Season 2

Disney Plus, 3 May 2023

The super-unique project that invites international animation studios to redo Star Wars in their style as shorts is back. And this time it’s way more international. Season 1 featured mainly Japanese anime studios, but Star Wars: Visions Season 2 features the likes of British studio Aardman (Wallace and Gromit), Ireland’s Cartoon Saloon, Korean Studio Mir and South Africa’s Triggerfish. That means there’s a collection of 9 all-new short films in unique new styles in Disney Plus’ Star Wars: Visions Season 2.

One of the few filmed sci-fi series in May, Silo sees a future community of people living hundreds of meters underground in a silo structure, because the surface world is unsafe. We don’t know why, and neither do they – so much time has passed, and no one remembers why they live down there.

Tale Of The Nine-Tailed 1938 (Season 2)

Amazon Prime Video, 6 May 2023

In this season, the Fox gets taken back to the year 1938, when Japan occupied Korea and he must find a way back to the present in Tale of The Nine-Tailed 1938.

The Gryphon

Not Sci-Fi and Fantasy but Worth a Look

Queen Cleopatra

Netflix 10 May 2023

We can’t call it a fantasy show, because it’s documentary-style, but it’s a Roman-Egyptian-Macedonian period piece, so might be worth taking a look at Netflix’s Queen Cleopatra
