NBC licensed the first season of Crossing Lines and aired it during the summer of 2013. It didn’t perform well in the ratings so the network cancelled the show. However, it was a success in other international markets so a second season was produced.
First season regulars William Fichtner, Donald Sutherland, Marc Lavoine, Tom Wlaschiha, Gabriella Pession and Richard Flood returned, along with Lara Rossi, who was introduced late in the first season. Guest stars for the season include Carrie-Anne Moss and Ray Stevenson.
