The Sherlock actor, who recently hinted to DS that he could be appearing in future episodes of the show, was apparently in the frame to succeed David Tennant as the Time Lord.
According to The Sun, Cumberbatch spoke to Tennant about the opportunity but decided not to pursue the role, which was eventually given to Matt Smith.
Cumberbatch said: "David and I talked about it but I thought it would have to be radically different.
"And anyway I didn't really like the whole package - being on school lunchboxes."
