When Mission: Impossible 5 is released later this year, it will have been nineteen years since the first instalment of the franchise hit the big screen. There has always been a gap between each one, as it took four years for the sequel, and then another six years for the third, and finally five more years for a fourth. Four years after the release of Brad Bird's Mission: Impossible - Ghost Protocol, and fans are hungry to see more of Ethan Hunt's adventures. The role of the Impossible Missions Force operative helped to establish Tom Cruise as an action star and major box office draw, and while the faces surrounding him have changed over the past two decades or so, he's remained a constant in the popular franchise. He may now be in his early 50s, but that's showing no signs of changing. After a string of moderately successful films, Cruise is once again a hot commodity following the release of Edge of Tomorrow, and the excitement surrounding Mission: Impossible 5 is huge. The movie is currently being shot, and while specific plot details have been kept under wraps, there's still plenty which is known about the highly anticipated release. Here, you'll find the ten things you most need to know about what Ethan Hunt and company will be getting up to in Mission: Impossible 5, along with all the latest casting news and rumours.
