After all these years, it feels like an absolute miracle to see Ewan McGregor and Hayden Christensen "teaming up" - so to speak - once again as Obi-Wan Kenobi and Darth Vader, but that's just what's happening, and we're not sure Ali can fully wrap his head around it. In this first-of-its-kind double-header 'Becoming...' interview, the pair dig deep on the prequels and geek out massively. They also discover an unfortunate issue with Ali's t-shirt, enjoy a tonne of fan-made merchandise and quote lines they've not said in years.
