Chloe Bennet, who currently plays record company assistant Hailey on Nashville, has reportedly become the sixth and final regular cast member on ABC's S.H.I.E.L.D. She will play Skye, and here's a description of her character:
Skye [is] a confident woman who is slightly obsessed with superhero culture and the shadow organizations that exist within it. She's edgy and can out-talk anyone with her unflappable nature.
Bennet joins Stargate Universe's Ming-Na as Agent Melinda May, Killing Lincoln's Brett Dalton as Agent Grant Ward, Hollyoaks actress Elizabeth Henstridge as Agent Gemma Simmons, The Fades star Ian De Caestecker as Agent Leo Fitz, and of course the incomparable Clark Gregg as Agent Phil Coulson.
