Laurie Sansom inaugurates his time in charge of the National Theatre of Scotland in epically ambitious fashion, in a co-production with the other National Theatre, Rona Munro's The James Plays. This trilogy of new history plays - a genre that's definitely back in fashion at the moment - looks at the first three King Jameses of Scotland, beginning right in the middle of the period Shakespeare looked at in his own English histories. At the start of James I - The Key Will Keep The Lock, Henry V (Jamie Sives) rules England, but not for much longer: The dysentery that would kill him is taking hold. In an attempt to leave one less source of conflict for his infant son to rule over, Henry frees his prisoner, King James of Scotland, who's been held hostage in England for 18 years. In return for being returned to his throne, James (James McArdle) is expected to pay a hefty ransom, which Henry hopes will leave the country too poor to wander South of the border; but James has other ideas.
