Filming was split into two blocks; the first (made up of episodes 1, 2 and 5) was directed by Aherne and the second by Simon Massey, who had previously worked on Ballykissangel.

In the United States, Strange has been broadcast by the cable television network Showtime, on one of its specialist subsidiary channels and in July 2009 the series started airing on Chiller.
