I am going to ask this in all sincerity: is it just me, or does it seem that Tom Cruise has gone mad?
In all sincerity, I think he has. I didn't see the episode of Oprah where he was hopping around (I haven't seen an episode of Oprah in 10 years or more), but I saw stills from it. He seemed pretty crazy.
I think he's always been nutty, but recently he hasn't been hiding it. Apparently he fired the publicist who used to keep him in control.
Probably your not-quite-so-standard midlife crisis; he must realize his glory days are past.
"or does it seem that Tom Cruise has gone mad?"
He made MI:3, I'd say so!
