Yeah, I see now. There was just that one shot where McCoy is in the foreground and Kirk behind him as they were apparently looking out of a window on some transport. His expression and features could have made him a doppelganger for Gary (Mitchell) Lockwood.
I love Urban's grim concept of space and space travel in trailer 2, "Space is disease wrapped up in darkness and silence." That is quintessential Leonard McCoy.
