John Cleese, Bill Nighy, and Kate Beckinsale are all lending their voices to characters in The Elder Scrolls Online.

Those four will also be joined by Alfred Molina (Doc Ock in Spider-Man 2) Michael Gambon (Dumbledore in Harry Potter), Lynda Carter (Wonder Woman), and A Clockwork Orange’s Malcolm McDowell.

As detailed by Bethesda Softworks, Cleese plays Cadwell, the cheerful and endearingly mad lost soul who is not afraid of anyone, even a Daedric Prince. Joining the cast as High King Emeric, Bill Nighy portrays a merchant prince whose luck and determination won him the throne. Kate Beckinsale takes on the role of Queen Ayrenn, the leader of the Aldmeri Dominion and Queen of the High Elves who is far more comfortable with a blade than her crown.

Alfred Molina takes on the role of Abnur Tharn, a wily old wizard and politician who is the head of the Empire’s Elder Council, and the de facto power behind the Ruby Throne. Lynda Carter plays Azura, the Daedric Princess of Dusk and Dawn from Skyrim who is a popular part of Elder Scrolls lore. Michael Gambon voices The Prophet, a mysterious blind man who guides the player through their journey to retrieve their soul; and Malcolm McDowell plays the key figure Molag Bal, an evil Daedric god from another plane who schemes to enslave the mortal souls of Tamriel.

"This extraordinary group of actors helps bring the distinctive characters in The Elder Scrolls Online to life," said the game’s director Matt Firor.

"In The Elder Scrolls tradition, we sought world class talent to add a deep and enriching component to the immersive world the series offers players."

The Elder Scrolls Online is due out for Windows PC and OS X on April 4, and PlayStation 4 and Xbox One sometime in June.
