Jai Courtney

Courtney built his early career in Australian television before breaking into Hollywood through a supporting role in the Die Hard franchise, a rising profile that led directly to a major role in the rebooted Terminator series soon after.

He took over Kyle Reese for Genisys's rewired timeline, playing a soldier who arrives in the past only to find history has already changed without him. An Australian actor who had recently broken out in the Die Hard franchise, he stepped into a role originated by Michael Biehn decades earlier.

He played a version of the character forced to react to a plot that upends his own remembered history in real time, one of the more conceptually unusual acting challenges any actor in the franchise has faced.
