Gervais deserved the heckles and he deserves the backlash against him and its not just from 'comedy snobs' (which is a horrible term), many other people are sick of Gervais, he even appeared on one of those awful list shows of 'Worst People of 2007' or whatever it was called last year. The media aren't as friendly to him as they once where and he seemed to be the main target at this years comedy awards. Angus made a few digs, when he was talking about 30 Rock he said "The one American comedy not to be ruined by a cameo appearance by Ricky Gervais" and when Eva Mendes was introduced as Ricky Gervais' number one fan he said "A title Ricky is not likely to give up so easy".
Corden is a bit of an arsehole anyway, but the heckles were deserved. Like Pete on this thread has stated there is no 'gag' with what Gervais is doing...he's bragging about having Emmys and Golden Globes, there is no gag there because he DOES have Emmys and Golden Globes...he says the British Comedy Awards are beneath him...again he has stated this as true in the past...there is no gag there...no matter whether he thinks it is hidden under this veil of "irony" the fact is what he's saying is true and just because he recorded a message doesn't constitute a 'thank you' instead it comes across as a way to sneer and belittle the other comedians that are actually there.
The other thing is, Gervais says he can't relate to British comedy anymore and that most of it is shite...and on the whole I actually agree...but Gervais is also part of that shite.
