But we’re willing to make an exception when it comes to The Muppets.

Yes, the cuddliest gang in showbiz have journeyed back to Victorian London to pay homage to their classic festive movie The Muppet Christmas Carol in a new ad for the US retailer Walmart.

The Muppet Christmas Carol first hit cinemas in 1992, and was the characters’ first cinematic outing since the death of the franchise’s creator, Jim Henson, two years earlier.

Director Brian Henson previously told HuffPost UK: “Of course I never expected we’d still be talking about The Muppet Christmas Carol 30 years later.”

“I was aware that, since we were adapting a classic piece of literature, it was important not to date the production, not to use hip contemporary language anywhere, or hairstyles, or anything like that,” he added.

“[And I was] mindful that, ‘if we do this right, it will always look right, no matter when or where you watch the movie’.”
