The 38-year-old British actor plays the titular role in the TV series and insists that while he has carved out a career in Hollywood, he isn't ready to turn his back on the programme because he loves playing the detective so much, reported Contactmusic.
"If we can keep the quality up, I can't imagine that I will ever get tired of being Sherlock. I'd love to play him as an old man," Cumberbatch said.
"I really, really love my job. I love sets. I love crews. I love theatres. I love audiences," he added.
