Hugh Grant and Chris Pine are not impressed with their 'diaper'-wearing 'Dungeons & Dragons' action figures: 'Shall we set them on fire?'

During their appearance on "The Late Late Show with James Corden," the actors saw their characters' action figures for the first time.

• "Dungeons & Dragons" stars Hugh Grant and Chris Pine reacted to seeing their action figures for the first time.
• The pair joked that their toy likenesses looked like they were wearing diapers.
• Appearing on "The Late Late Show With James Corden," Grant then said they should "set them on fire."

Hugh Grant joked with Chris Pine about burning their "Dungeons & Dragons: Honor Among Thieves" action figures after seeing them for the first time.

The pair star in the new movie based on the famous fantasy roleplaying game, and were presented with their toy likenesses during an interview on "The Late Late Show With James Corden" on Wednesday night.

"I am slightly worried about my big blue diaper or chastity belt," Grant said after being handed the action figure of his character, Forge Fitzwilliam.

When Pine, who plays Edgin Darvis in the movie, received his action figure, he added: "I understand what Hugh's saying. I'm wearing some sort of brown diaper. I look better in blue."

Grant then interrupted Pine to say: "Should we set them on fire? That's what I used to do. Did you ever have Action Man? My brother and I had lots of Action Men and we burnt them. Why did we do that? We put them on the zip wires and set them on fire and then when we'd run out of Action Men, we did it to our cousins' Barbie dolls."

Action Man is a British line of toy soldiers, similar to G.I. Joe action figures in the US, and launched in 1966, according to the company's website.

Despite starring in a movie about the tabletop game, Grant recently said on "The Late Show With Stephen Colbert" that he has never played "Dungeons & Dragons."

Grant mentioned that Pine tried to get him to play the game on set, but the actor lamented that movie sets are no longer as exciting as they once were.

"Films are so weird now. They are weird because, in the old days, by the end of the second week, you were all getting drunk in the evening and having dinner and falling in love with each other and all of that," Grant said. "All of that stopped because of telephones. Everyone goes home and looks at Twitter. It's so sad."

Grant added that there would be more set affairs if phones were banned on set.

"Dungeons & Dragons: Honor Among Thieves" is in theaters on Friday.
