Fans of spy thrillers might already be familiar with the long-running BBC series Spooks, which aired on a few different US networks under the title MI-5 and has since arrived in its entirety on Netflix. As well as being an excellent series in its own right, Spooks also featured a number of actors who either were or would go on to be major stars, including Richard Armitage, Matthew MacFadyen, and David Oyelowo.

Although it was cancelled in 2011, Spooks was popular enough to earn a follow-up movie called Spooks: The Greater Good, which is set for UK release this summer. Peter Firth reprises his role as MI-5's head of counter-terrorism, Harry Pearce, who is blamed for the escape of dangerous terrorist Adam Qasim (Elyes Gabel) and disappears off the grid soon after. Kit Harington (Game of Thrones) joins the Spooks universe as Will, Harry's protégé, who is called upon to investigate the situation as evidence of an impending attack on London builds.

The new teaser trailer for Spooks: The Greater Good shows Harington enthusiastically jumping into the action role: leaping through windows, crashing cars, dodging snipers, and making a general effort towards preventing London from being blown up. Spooks: The Greater Good was directed by Bharat Nalluri, who has previously worked on a number of different TV shows (and directed the pilot episode of The 100), while the script was handled by regular Spooks writers Jonathan Brackley and Sam Vincent.

The extent to which audiences will need to be familiar with the original series (no small demand, since it's 10 seasons long) is unclear from this teaser. However, since the principal cast is almost entirely made up of actors who weren't in the series, it seems likely that Spooks: The Greater Good will be a continuation of the spirit of the show, rather than the plot.

It might not have the promised silliness of Kingsman: The Secret Service, but this could a pleasing follow-up for fans of the original series - and a solid British spy thriller for everyone else. Let's hope a full-length trailer gets released soon.

Spooks: The Greater Good releases in UK theaters on May 8th, 2015, but doesn't currently have a US release date.
