However, there is only so many insults the actor can take judging by his response to Speidi's angry rants about him in scenes set to air on the Channel 5 show tonight.
The 68-year-old hints that something is boiling under his cool exterior following Spencer's epic rant, in which he branded him "a piece of s**t".
In a teaser from the latest instalment, James C is heard commented: "The only thing that I'd say, in all seriousness, that this might be a game but I take everything personally."
The Games Of Thrones star then chillingly added: "It could end up being nasty."

He then explains that it would be pointless to get annoyed as Heidi, 30, and Spencer are simply playing a game.
But, James C then jokes that on the outside he would maybe do something more than would be normal: "Like bite your f**king nose off."
