Vinnie McCabe as a Lannister bannerman.
Vinnie McCabe (or Vincent McCabe) is a British actor.
In Game of Thrones he was originally announced as playing Lord Rickard Karstark, first seen in the first season finale, Fire and Blood, but this appears to have been an error. Steven Blount played Karstark whilst McCabe actually played one of the Lannister bannermen in the same episode, speculated to be either Lord Swyft or Lefford based on the dialogue used from the books.
