Writing on his blog after the NBC show's Thursday finale, the Cemetery Junction comedian appeared to take issue with the mass of famous faces drafted in to conclude the season.
He said: "Watching the Office finale may remind some of the Chris Martin episode of Extras... If you're going to jump a shark, jump a big one. Still we've had a good innings. I assume most people know I didn't do the US remake for the art."
However, Gervais has since returned to the site to clarify his comments and reaffirm his pride in the Stateside adaptation.
He wrote: "Sorry, who dissed The Office finale? I f**king didn't, that's for sure. I simply said it's different to the original which I created and made with different ambitions. What's wrong with that?
"The bit about it 'jumping the shark' and being like Chris Martin in Extras was meant to be a little self-deprecating in-joke. I myself, did a fun but pointless, over-hyped cameo in the episode too, remember. I did it for a laugh like everyone else, I assume. I certainly wasn't dissing anyone involved more than myself."
He further vented: "The US version of The Office has probably made me ten times the money that the UK version did. I wouldn't knock it. It's still my show. All I said was I do it for different reasons. That is simply what they call the truth. Hope that's okay. I believe I am still entitled to an honest opinion. After all, every other c*** is."
