Neil Pearson and Nicola Stephenson are joining the cast of Waterloo Road.
The new additions, who will play teachers Vaughan Fitzgerald and Allie Westbrook, have already started filming their scenes for the 10th series of the BBC drama, which will screen in 2014.
Neil, who is best known for his role as Dave Charnley in Channel 4 comedy Drop The Dead Donkey, said: "Waterloo Road has a long and successful history, an impressive list of alumni, and a highly talented and enthusiastic cast. All of which makes me very excited to be joining my new school."
Nicola's acting credits include parts in Brookside, Holby City and Clocking Off.
Waterloo Road's executive producer Brian Park added: "We're absolutely thrilled to have such high-quality actors like Neil and Nicola on board. Neil is one of the country's most recognised television acting talents and Nicola's drama credentials speak for themselves.
"This new pairing are going to make quite an impact on the school when they arrive on screen. We know the viewers are going to love watching them in action," he teased.
BBC Scotland's head of drama Christopher Aird said: "We're delighted to welcome Neil and Nicola to the wonderful Waterloo Road cast. They are both firm favourites in households across the UK, having played iconic characters in some of Britain's best-loved shows. We're thrilled they'll be making their mark on Waterloo Road next year."
The ninth series of Waterloo Road is shown on Thursdays on BBC One.
