Much like the Super Bowl in the U.S., Christmas ads in the U.K. are now getting their own elaborate teaser spots—as seen in Asda’s 60-second ad below, building anticipation for a full 90-second film starring Michael Bublé that’s due to drop this Saturday (Nov. 4).

The teaser features Asda colleagues hanging out in a break room who hear a weird gurgling sound at the clock strikes midnight on Nov. 1. They investigate—and soon find the festive source of the mystery.

Asda typically creates high-profile spots for the holiday. Last year, the retailer used some nifty special effects to insert Buddy the Elf from the movie “Elf” into new scenes set at one of its stores.

“At Asda, we absolutely love Christmas and this year we’re once again on a mission to bring that warm, festive feeling to households across the U.K.,” said David Hills, Asda’s chief customer officer. “Today, we’re putting the speculation to rest and confirming that the legend that is Michael Bublé is partnering with us this Christmas to put on a showstopping performance.” 

He added: “With Bublé’s undeniable ability to spread seasonal smiles and our commitment to quality, at great value, we’re a match made in heaven, proving Asda is a one-stop-shop for families seeking magic this Christmas.”
