Canadian actor, known for Reign and Shadowhunters, who played the Section 31 captain Leland, later the host of the artificial intelligence Control, in Discovery's second season.
Alan van Sprang is a Canadian actor, born in 1971, whose credits include King Henry II of France in Reign, Valentine Morgenstern in Shadowhunters, The Tudors and several films for George A. Romero.
In the second season of Star Trek: Discovery he plays Leland, the Section 31 officer who commands a covert ship and recruits Philippa Georgiou and Ash Tyler. The season reveals his part in the deaths of Michael Burnham's parents. In Perpetual Infinity the threat-assessment system Control takes over his body with nanites, and from then on van Sprang plays the machine wearing Leland's face.
The possessed Leland leads the attack on the Discovery and the Enterprise in Such Sweet Sorrow, where Georgiou destroys him in a magnetised spore chamber.
