Gael García Bernal and Irish star Laura Donnelly will make their MCU debuts next month.

The mysterious and macabre Disney+ special 'Werewolf By Night' had a preview screening for critics recently, and early reactions are full of praise for Marvel's first black and white feature.

Gael García Bernal will star as Jack Russell AKA Werewolf By Night who will have to face off against a group of quite barbaric monster hunters on one fateful night. The group gathers at Bloodstone Temple to have some fun in a deadly competition, competing against each-other for a special object. However, the titular Werewolf is believed to show themselves, making for a horrifying night for all.

As we can see from the trailer, the hour-long Halloween special is inspired by classic 1930s and 1940s horror films such as 'Dr. Jekyll and Mr. Hyde', 'Dracula', and of course 'Werewolf of London' and 'The Wolf Man'.

We also catch a look at Elsa Bloodstone (played by 'The Nevers' star Laura Donnelly), who is basically Marvel's answer to Buffy The Vampire Slayer; and also Man-Thing, who was briefly teased in 'Thor: Ragnarok'.

First-time director Michael Giacchino is being highly praised for his take on the comic book character (referred to as "Werewolf"), who first appeared in Marvel Comics back in 1972. Giacchino has branched out to directing following a very successful career as a music composer ('The Incredibles', 'Spider-Man: No Way Home', 'The Batman').

The synopsis for the Disney+ special is as follows: On a dark and somber night, a secret cabal of monster hunters emerge from the shadows and gather at the foreboding Bloodstone Temple following the death of their leader. In a strange and macabre memorial to the leader’s life, the attendees are thrust into a mysterious and deadly competition for a powerful relic—a hunt that will ultimately bring them face to face with a dangerous monster.

Here are some early reactions to 'Werewolf By Night', which begins streaming on Disney+ from October 7. Judging from the tweets, we're going to be sleeping with the light on for a few days after watching - which makes us all sorts of excited.
