They say death and taxes are the only two certainties in life. I say they forgot one. Clearly, every red-blooded American can also count on finding at least one spine-tingling, show-stopping, blood-curdling, totally exclusive casting roundup a week in the Ausiello Files. Case in point:

Las Vegas‘ Vanessa Marcil is rolling the dice on a recurring gig at Lipstick Jungle. She’ll play Josie, a very attractive (duh!) up-and-coming music manager who promises Shane (Paul Blackthorne) a gig scoring music for a cool indie feature.

• It’s official: David Arquette is this season’s go-to TV guest star. Fresh off his recently wrapped stint as a “freshcort” on Pushing Daisies, Arquette has landed what could be My Name Is Earl‘s funniest karmic-redemption subject yet. His character, Johnny, is a small-town Evel Knievel-esque stuntman whom Earl wants to cross off his list for sleeping with his girlfriend. There’s just one problem: A past accident has left Johnny with short-term memory issues and an existence not unlike Bill Murray’s in Groundhog Day. Good luck with that one, Earl!

• It’s a Martin reunion! No, not on TV Land, on Everybody Hates Chris! Tisha Campbell-Martin is re-teaming with her old Martin sidekick Tichina Arnold for a multi-episode Chris arc. Campbell-Martin will channel Peaches, a sexy, edgy, vibrant ghetto princess who moves back to Bed-Stuy after a stint in prison and strikes up a frenemyship with Arnold’s Rochelle.
