As previously reported, House of Cards season 2 casting got underway in Maryland last month, and the show is currently filming, as confirmed Wednesday by Kate Mara:

A couple more pieces of casting news came out this week, as the show has picked up Jimmi Simpson and Kate Lyn Sheil for the new season.

TheWrap reports that Simpson has been cast in a recurring role on the show, but the nature and identity of his character is “being kept hush-hush by producers”. Simpson is known these days for his role on A&E’s Breakout Kings, and It’s Always Sunny In Philadelphia fans will know him as the unforgettable Liam McPoyle (lead image).

BuzzFeed reported earlier this week that Kate Lyn Sheil will also appear in the upcoming season. Her role is also being kept secret. Sheil has appeared in V/H/S, Sun Don’t Shine and Somebody Up There Likes Me.

Mad Men’s Sam Page and Deadwood’s Molly Parker were previously confirmed for season 2.

House of Cards Season 1 was released on DVD and Blu-ray on Tuesday.

According to BuzzFeed, the second season will have 13 episodes. There is no release date scheduled yet.
