Was watching some videos of Cruise with Flatlander and I've typed Tom Cruise as NiFe or INFJ in the past, and this video gives a very cear idea of his cognition both in terms of thinking and body language:
mh, actually he's typed FeSi in the "vip" list, he can seem an NiFe for the warm articulation of his voice because of Fe (very similar to Steve Jobs in this video, i have to say), but if you watch carefully his eyes you can see that they're constantly darting around the room, and sometimes they blinks over the necessary, you can see this also in the most recent videos Ni eyes are more relaxed and slower in the movements. Other thing, he's certainly a J lead because he is more rigid in his posture than a common P lead, you can also see the exacting/demonstrating hands that are a sign of J lead.
He does have this "mean" look in some of his old/young pictures where he poses in this badass/hard way, making his eyes look a tinge more piercing, but I think that's for dramatic effect. At rest his eys are Ne.
