Might 'Arrested Development' season 4 be the true Holy Grail of comedy we're all hoping it to be?  The more of our favorite comedic stars it adds, the more likely that possibility seems.  'Parks and Recreation' breakout and 'House of Lies' star Ben Schwartz is the latest reported to join the cast, but who will he play?  Will the wall of secrecy around all of 'Arrested Development' season 4's guest castings come tumbling down?

'Arrested Development' season 4 must be pretty flush with cash, to attract the charms of Jean-Ralphio.  TVLine has managed to confirm that occasional 'Parks and Recreation' guest and current 'House of Lies lead Ben Schwartz will join the Bluth Family for their spring 2013 Netflix reunion season.  As with many of the other guest stars to be cast, Schwartz' role is being kept well under-wraps for now.

Schwartz is the latest to add to a star-studded reunion season that features appearances 'Up All Night's Chris Diamantopoulos from all three stars of Comedy Central’s ‘Workaholics,’ Mad Men’s’ John Slattery, Isla Fisher and Terry Crews, as well as returning series players Jeff Garlin, Liza Minnelli, Judy Greer, Henry Winkler and Scott Baio.

Details and set photos continue to pour out, but for now, new additions to the cast remain relatively well-hidden.  Whom do you think Ben Schwartz might play in 'Arrested Development' season 4?
