I wouldn't quite say he 'had a go'. But this was a while back, before Mack was famous in his own right for Not Going Out and maybe WIL - so this is a long time. Ross was labouring the point that although Mack had been in many things - sketch shows, for instance - he couldn't quite remember him as being famous for anything. It was a sort of true, edgy observation - and the kind of thing that helped differentiate Ross from the cosy Aspel/Parky brand of questioning. But it seemed to me that Mack was just having to sit there and put up with it, being a C-list star (at the time) and having to use this outlet to promote himself.
Same when Daniel Craig was in contention for the Bond role, and somewhat derided for it, being no great looker at the time. 'I'm thinking... 'craggy',; joshed Ross to Craig, being interviewed for another gig, and Craig had this wan slightly forced smile. On an admittedly craggy face. Of course, once Craig had bagged the Bond role, it was all 'and I'm really pleased you got the role'.
Ross also rudely shut down Penelope Cruz when she was being long-winded on a story, saying 'Alright, you're being really boring now' and she was quite shocked. But tbf, I understand she was being a bit boring and back then, there was a bit of bite to social discourse. You saw it with the likes of Chris Evans, Graham Norton originally - he can still be a bit edgy, also Clive Anderson. It does run its course, however, because none of it is very happy or jolly, sometimes it comes from a dark place. And ultimately because of this folk want to switch gears and go 'happy' - almost One Show stuff. Unfortunately on the larger stage, folk then might fall for any drivel the likes of Boris and Trump peddle, it makes you feel good so it is good, it seems to me. It's easy to pick holes in Boris and Trump but they've got that thing going on where, if you do that, you're the 'nasty' and 'negative'.
