On DS9, either he hunched over a lot or (more likely) was always surrounded by tall actors.
And they used a camera angle to exaggerate his height, I think.
.
Various web sites list Tom Cruise as 5'5" (barefoot) to 5'7" (with shoes), but I wouldn't trust their accuracy.
And you know he looks like a big man in his movies.
The airport placement was wrong (too close to MGM / Mandalay Bay etc, plus didn't look right) having just came from Vegas and having shot video from both ways I noticed, as always the guy you thought did it didn't ... The scene in the station with the "kid" was hilarious.(convincing him to cough up some info)
