Amazon Prime's Secret Level voice cast from Terminator to John Wick star

A new Amazon Prime series now streaming boasts a star-studded cast, including familiar voices from John Wick and Terminator.

Secret Level is an anthology series from the creative minds behind Netflix's Love, Death + Robots. It brings to life over a dozen cherished video game franchises, from Pac-Man to Dungeons and Dragons.

The first eight episodes began streaming on December 10, with the remainder of the series set to be released on December 17. Some big-name stars have already made their mark in the early instalments.

Episodes vary in length, ranging from just a few minutes to less than 20 minutes in total, so there isn't much time to catch a famous voice. The Amazon Prime Video app tends to automatically play the next episode before fans have a chance to spot names in the credits.

So, here are some of the most notable actors lending their voices to the series and the episodes they feature in.

The first voice that stands out throughout the series belongs to action star Arnold Schwarzenegger, known for his roles in The Terminator and Predator. Many fans anticipated the actor-turned-politician's appearance in the series, but speculation about which part he would play has proven incorrect, reports the Daily Record.

In a surprising twist, Arnold Schwarzenegger takes on the role of King Aelstrom in an episode based on the role-playing game New World. He's not the only ex-Terminator to feature; Gabriel Luna, who also played a version of the sinister robot in the latest instalment of the franchise, Dark Fate, joins him as King Zimah.

The Unreal Tournament episode, which centres around a robotic uprising, features the voice of Elodie Young, known for her role as Elektra in Netflix's Daredevil series. She appears as the Gamesmaster.

Mark Sheppard, a Supernatural series alumnus, appears in the Warhammer 40,000 episode, voicing Ultramarines Orbital Command and Astropath. Clive Standen, recognised from Vikings, returns to his role of Demetrian Titus from the original Space Marine 2 game.

Emily Swallow lends her voice to Puck in the Pac-Man episode. Known for her roles in Star Wars spin-off The Mandalorian and Supernatural, her voice will be familiar to many.

Finally, Hollyoaks actor and former Strictly Come Dancing finalist Ricky Whittle, known for his roles in American Gods and The 100, features in the episode adapting first-person shooter Crossfire, playing the character Cross.

The Armored Core episode, inspired by the series of third-person mech action games, boasts an impressive cast list. It features Arnold Schwarzenegger's son, Patrick Schwarzenegger as The Kid, and Temuera Morrison, known for his role as Jango Fett in the Star Wars prequels, as Old Salt.

Morrison also took on the mantle of Boba Fett, the clone son of the bounty hunter, in the spin-off series.

Adding to the star-studded line-up is Keanu Reeves, famed for his roles in John Wick and The Matrix. He not only lends his voice to a character but his likeness is also used by the animators for The Pilot.

This isn't the first time Reeves has contributed his voice and image to a game-related project. He previously appeared in CD Projekt Red's ambitious RPG Cyberpunk 2077 as rock star Johnny Silverhand.
