Apple TV has had some big stars in its time, already, but I think it's fair to argue that few have been bigger for it than Idris Elba – his thriller show Hijack was a real highlight a couple of years ago, helping to propel the streaming service to greater heights of popularity.
Now, with whatever level of story improbability you'd like to name, the show's back for a second season, with Elba's Sam Nelson once again caught in the middle of a hostage situation aboard a fast-moving vehicle. This time, though, it's a subway train in Berlin, rather than a long-haul flight, meaning he might need to come up with some new tactics to avert disaster.
