Well, I just watched it purely as a result of seeing this thread in the Telly Addicts list.
I am astounded at how attractive TC is, he is ageing beautifully. I think he's had "something" done, but I'm not sure what, maybe a face-lift or something. He doesn't seem to have fillers, but something was just a bit different. Good work, whatever it is.
Also, if you watched his mouth when he was talking, it was very Gary Barlow-esque. Same mouth shapes/movements when talking seriously.
As others have said, he takes himself so incredibly seriously. He also clearly adores being the centre of all the attention. He's textbook narcissist - the name dropping; the way he holds court when telling a story, making eye contact with each of them in turn; the way he asks questions of all of them, to make them feel privileged that they're worthy of his time; the way he said congratulations in a patronising way to each of them regarding roles they had won. Graham asked Jennifer and Miles a few questions, but every one referred to what it was like working with Tom. On a normal show, Jennifer would be asked about what it's like being married to Vision himself etc, but they had clearly been booked to discuss Top Gun only, and not to deviate from it.
None of it was done in a lighthearted, off the cuff way, it is exactly as others have said - TC has become a real-life character and probably doesn't even know how to be a person any more.
And when he was joking with Miles, it was very "HAHAHAHA" through slightly gritted teeth, then he actually said "HAHHA I'll crush you, haha" to put him firmly back in his place.
I would not want to cross him.
