The 35-year-old British actor landed a voice role in the famous animated sitcom following a chance meeting, reported In Style magazine. "I was at a meeting in the same place 'The Simpsons' is recorded and heard there was a part going in an episode.
I said, 'I hate to muscle in here guys but could I record it?' Next thing, I'm standing in a room with all those famous voices; Bart, Marge, Homer, Lisa," Cumberbatch said.
The actor, who shot to fame playing iconic detective Sherlock Holmes in TV series 'Sherlock', was thrilled to be a part of the cartoon because he likes to take on as many varied roles as possible.
"I like treating every job as the first time and to do that, I'll vary the work, so I'll be a knuckle head and run around with girls and guns, then I'll slow it down and do something different like Edwardian drama 'Parade's End'," he said.
In 'Parade's End', Cumberbatch had to undergo a radical physical transformation to play aristocrat Christopher Tietjens. "I wore a fat suit under my clothes and had bumpers in my cheeks. They attach like a brace to your teeth to make your face look plumper," he added.
