I have many favorites in the TAC video, but I think my most favorite happens after Javert's suicide and Philip is sitting behind the cast as they sing the finale. He's turned around in his chair and is watching the chorus and orchestra with evident enjoyment. Then, during the ovation, he blows a kiss to the chorus and orchestra to show his appreciation.
I'm also amazed at how surprised and pleased he looks at the huge ovation he gets during his bow and then immediately looks back for Colm and brings him forward. He then steps back and enthusiastically joins in the applause for him.
At one point during the ovation, he turns to Colm and it looks like he says, "It's too bad we won't be back tomorrow." I like that part because he evidently enjoyed himself and perhaps was pleased at the audience response to his playing Javert again.
