The Boondocks Returns to Adult Swim for Fourth and Final Season (Trailer/Pics)

The Boondocks’ fourth and LAST season commences  Monday, April 21 at 10:30p.m (ET/PT) on Adult Swim.

In The Boondocks, Robert “Granddad” Freeman (John Witherspoon, FridayAfter Next) is the cantankerous legal guardian of his rambunctious grand kids Huey and Riley (Regina King-Southland and Ray) and has moved them from the south side of Chicago to the quiet and safety of “The Boondocks” (in this case, suburban Woodcrest), hoping that he can ignore them altogether and enjoy the golden years of his life in peace.  But Huey, a 10-year-old left wing revolutionary, is determined not to enjoy the affluence of suburbia.  This attitude is seconded by his 8-year-old brother, Riley, a proud product of contemporary rap culture.  Although they torture each other and provoke the neighborhood, they are no match for Granddad, who is eccentric even by “crazy-ass-old-black-man” standards.  Gary Anthony Williams (Boston Legal) as Uncle Ruckus, Gabby Soleil (Johnson Family Vacation)  as Jazmine Dubois and Jill Talley (Camp Lazlo) as Sarah Dubois round out the cast, with Cedric Yarbrough (Reno 911!) returning as the voice of fan favorite Colonel H. Stinkmeaner in addition to Tom Dubois.

The new season finds Huey, Riley and Granddad encountering a roster of characters, both new and familiar, in uproarious situations, including Granddad’s dating a long lost Kardashian sister; their friend Tom DuBois acting as R&B bad boy “Pretty Boy Flizzy’s” lawyer in exchange for relationship advice; Granddad’s love affair with Siri on his new iPhone; and the Freemans’ foray into the lethal black market of the hair-care industry à la “Breaking Bad.”  Throughout the final season, an eclectic mix of hip-hop artists, actors, comedians and media personalities will voice guest characters on the series, including Jenifer Lewis (Think Like a Man), Dennis Haysbert (24), Busta Rhymes, Snoop Dogg, Ghostface Killah, CeeLo, Lil Wayne, Donald Faison (Scrubs), Aisha Tyler (Balls of Fury), Kym Whitley (Reno 911!), Tichina Arnold (Everybody Hates Chris), Mo’Nique (The Parkers), Marion Ross (Happy Days), Tavis Smiley, Terry Crews (Brooklyn Nine-Nine), Bill Duke (X-Men: The Last Stand), and Cedric the Entertainer (Talk to Me).  Reprising their guest roles from last season are Xzibit, Charlie Murphy, MTV’s Sway and Katt Williams, among others.
