Martin Ellacott, Robin’s younger brother, has been cast for the TV series (which, according to IMDB, is now simply entitled Strike).

Joe Johnsey is going to play Martin, an amusing character who enjoys taking the mickey out of his sister (typical little brother, eh?). We’re hoping that he calls Strike “Hopalong” in the TV series as well.

Joe looks like he could be Robin’s sister. What do you think?
