The two actors were sitting side by side on The Graham Norton Show when Ford turned to the Star Trek: Into Darkness star and handed him a huge chunk of praise.
The Star Wars icon said, "I didn't get a chance to say what a big fan I am of yours... The Sherlock Holmes thing is amazing."
A visibly stunned Cumberbatch responded, "Thank you very much. Wow, that's a bit of a moment. Thank you very much."
The Sherlock star then stood up and quipped, "I can retire now, I'm going."
The show was broadcast in the U.K. on Friday (11Oct13).
