Arrow Season 6: Lost’s Michael Emerson cast in mysterious role

Star City is getting a mysterious new resident this year in the form of Lost and Person of Interest star Michael Emerson, though few character details have been revealed.

The news came during San Diego Comic-Con this weekend, and judging by the reaction of the cast in their TVLine interview, they’re as excited as we are (skip to 2:45).

Emerson, as expected, will be an antagonist for Oliver and the gang, but as part of a group rather than as a main adversary.

Watch the trailer for season six below.

Arrow airs on Sky1 in the UK.
