Get a sneak peek of Super Bowl commercials

Chrissy Teigen and John Legend star in a spot for Hyundai's Genesis vehicle.

Chris Evans and his Beantown buds touting Hyundai's "Smaht Pahk" feature in an ad released Monday, but Wednesday saw more new ads drop online before Sunday's big game.

They include:

Chrissy Teigen and John Legend star in a spot for Hyundai's Genesis vehicle, touted as the replacement to "old luxury" car brands.

Rainn Wilson from "The Office" stars as the beleaguered CEO of Sliced Bread Inc, in the new Little Caesar's delivery commercial, while on the other side of the fitness coin, John Cena and Jimmy Fallon hawk waist-conscious Michelob Ultra beer.

And as for drinks of the soft kind, Emmy winner Bryan Cranston breaks bad -- and doors -- aping Jack Nicholson in The Shining, in an ad for Diet Mountain Dew.

Walmart is turning to switching things up from last year's "movie cars" theme to iconic space adventurers for this year's spot. Taking advantage of the retailer's pick up program will be Space Ranger Buzz Lightyear from the "Toy Story" movies, Star-Lord's Milano from "Guardians of the Galaxy," the Starship Enterprise, Alex Winter in character from the "Bill & Ted" movies, and others.

Lil Nas X saddles up with Sam Elliot, John C. Reilly and Billy Ray Cyrus for a Doritos ad referencing the musicians' smash hit, "Old Town Road."

Also, the animated show "Rick and Morty" takes center stage in a Super Bowl spot for Pringles, which starts by discussing the inanity of such commercials but quickly manages to turn into a nightmare dystopian killer-robot scenario, which is par for the course for the hit series.
