Truth be told, the first Gemini Man trailer didn't quite sing. Ang Lee’s upcoming sci-fi thriller boasts a killer, Looper-esque concept – a hitman is pursued by a younger clone of himself – and is based on an idea that’s been floating around Hollywood for decades. But where the previous teaser didn’t quite hit the spot, a second trailer has arrived with a more confident and intriguing look at the film – introduced by none other than a de-aged 1989-era Will Smith.
