Sherlock is a very on/off TV show. That comes down almost exclusively to how hard it is to get everyone's schedules on the same page. Benedict Cumberbatch and Martin Freeman are some of the biggest stars nowadays, so that must be tough.
However, we do have a Season 4 coming up, but with no commitment to the future, it does pose the question, when will this series end, or perhaps more importantly, how? Speaking to TVLine, Mark Gatiss gave his two cents, explaining he'd like to see the two characters end up where the classic portrayals start.
Right at the beginning, we said, wouldn't it be fun — because we start with the first meeting, which is very rarely dramatized — if we actually ended up with them at the same age as Basil Rathbone and Nigel Bruce? That would be a really interesting place to be with Benedict and Martin, having started so early in their careers as young men
For those wondering, Basil Rathbone was 44 when he was in 1939's Sherlock Holmes. Benedict Cumberbatch is currently 40, so that really isn't long to go.
