The Canadian-American star Stana Katic has closed the deal to return to 'Castle' for its upcoming 8th season.
The 37-year-old actress will be signing a new contract along with the 'Serenity' star Nathan Fillion, who has already committed to come back, as their original ones expired at the end of 7th season, Deadline.com reported.
The veteran series will be in the hands of new show runners this time as Alexi Hawley and Terence Paul Winter will be writing the show for TV's favourite couple.
