VIDEO: Will Ferrell & Cast of THE OFFICE Bid Viewers Farewell in New Web Series

NBC and John Krasinski have partnered to produce a farewell web series to THE OFFICE, featuring cast members and guest stars, including Will Ferrell. Entertainwent Weekly has just debuted the first installment - check it out below!

The 10-episode series will premiere throughout the upcoming weeks, leading to the series finale on May 16.

In the series, Andy Bernard (Ed Helms, "The Hangover"), the preppy salesman and die-hard Cornell alumni whose endless and unique musical talents keep The Office entertained, is the new Dunder Mifflin Scranton regional manager.

Reporting to Andy are the loyal, and often times unmotivated, staff including sales rep Jim Halpert (John Krasinski, "Promised Land," "Away We Go") who shares his working space with Dwight Schrute (Rainn Wilson, "The Rocker"), the arrogant assistant to the regional manager whose responsibilities have expanded as he became the new owner of The Office building. Pam Beesly Halpert (Jenna Fischer, "Hall Pass," "Blades of Glory") is The Office receptionist-turned-office administrator whose office romance with Jim led to marriage and the birth of their children, Cece and Phillip. A surprising bromance has also formed between Andy and the ambitious distribution coordinator, Darryl Philbin (Craig Robinson, "Hot Tub Time Machine"), who moved his office from The Warehouse to the main building.

Also starring are Leslie David Baker ("Malcolm in the Middle"), Brian Baumgartner ("Arrested Development"), Kate Flannery ("The Heir Apparent"), Angela Kinsey ("Furry Vengeance"), Paul Lieberstein (writer, "King of the Hill"), Oscar Nuñez ("The Proposal"), Phyllis Smith ("Bad Teacher"), Creed Bratton (former member of The Grass Roots), Ellie Kemper ("Bridesmaids") and Catherine Tate ("Gulliver's Travels"), Jake Lacy ("Better with You") and Clarke Duke ("Greek").

"The Office" is executive-produced by Ben Silverman, Greg Daniels, who developed the series for American audiences, Ricky Gervais, Stephen Merchant, Howard Klein, Paul Lieberstein, Brent Forrester and Dan Sterling.

Since its premiere on NBC in March 2005, "The Office" has established itself as a genuine hit, earning prestigious television honors such as the 2006 Emmy Award for Outstanding Comedy Series, 2006 Peabody Award, 2006 & 2008 AFI Honors, Producers Guild Award, Writers Guild Award, SAG Award for Outstanding Performance by an Ensemble in a Comedy, Ace Eddie Award for editing and a Television Critic's Association Award for Outstanding Achievement in Comedy.
