Thursday nights on ABC — known by some as "ShondaLand" or T.G.I.T. — are full of more recognizable celebrities than many red carpets are. Even the recurring actors on Shonda Rhimes' shows have notable acting chops in their back pockets. Gaius Charles, who played Brian "Smash" Williams on NBC's Friday Night Lights, played Dr. Shane Ross for Seasons 9 and 10 of Grey's Anatomy. And Joe Morton has played Rowan "Papa" Pope for the last few seasons of Scandal, winning an Emmy this year for his portrayal of the malevolent role.
In fact, Rhimes has ensured that the worlds of her shows are full of talented, established faces, from the leads down to guest parts — often transforming a role with a multi-episode arc into a multi-season story. As she has so carefully crafted her casting sheets, it is no surprise that the guest stars for this season are just as well-known. While many have already been announced for the 2014–2015 season, there are sure to be more coming as the year unfolds.
