The actor, who plays Ken Barlow in the ITV1 soap, said that it is good to still have nerves after 50 years and confessed that he felt apprehensive when filming scenes with his sons, Linus and James.
According to PA, he said: "I always get nervous. The day you don't feel nerves is probably the day you should think about moving on."
Speaking of working with his sons, he added: "The fact we worked on the scenes together at home really broke the ice."
Linus Roache plays Lawrence, Ken's long-lost son, while James Roache is playing Lawrence's son.
