When we got a chance to sit down and talk to Karl Urban and John Cho - Bones and Sulu, respectively - we had a huge number of questions for them.

Why doesn't Bones where the doctor's dress smock thing in Star Trek Beyond? Why doesn't Sulu fence like Sulu does in the original series? Was there a reference to Bones' gigantic beard / Ankh necklace in Star Trek Beyond? Endless questions, really.

However, as per usual, we ended up blabbering on with them about their favourite Star Trek film and, we've got to admit, Karl Urban's choice was pretty surprising.

Take a look.
