'Supernatural' will reprise one of its favorite guest stars when nerd goddess Felicia Day makes her third appearance in upcoming April 24 episode "Pac-Man Fever,' but its latest casting is a divine nerd all his own. 'Revenge of the Nerds' star Curtis Armstrong has been announced to appear in May 1 episode "The Great Escapist" as God's go-to angel "Metatron," but will he be able to help Sam and Dean with the trials? Get a sneak peek of 'Supernatural's endgame inside!

The 'Supernatural' war between angels and demons will surely heat up when the long-running CW returns for its final four episodes of the season on April 25, and the CW has tapped some serious 'Revenge' for the fight. Via TVLine, we've learned that 'Revenge of the Nerds' star and beloved comic actor Curtis Armstrong will appear as Metatron, historically known as the personal scribe of God.

Seen as something of a cross between Obi-Wan Kenobi and 'The Usual Suspects' Verbal Kint/Keyser Soze, Metatron will reluctantly aid the boys when they seek help decrypting the third trial, now that Kevin Tran has gone missing. In addition to appearing in the final three episodes of the season, Armstrong's role may recur into the ninth year as well.

We've included pictures of the May 1 episode featuring Curtis Armstrong below, so have a look and tell us how you think 'Supernatural' will close out season 8!
