Pepsi released new Sierra Mist Undercover Orange and Sierra Mist Free Undercover Orange Free. The drink is tied to Warner Bros.’ “Get Smart” movie featuring Steve Carell as an undercover agent, Anne Hathaway and Dwayne “The Rock” Johnson. The new Sierra Mist has a Mandarin Orange flavor, but in keeping with the movie theme, is disguised as a clear liquid with no orange coloring. The drinks are on shelves for a limited time, from May through July. The beverages were released in 20-ounce bottles and 12-ounce 12-packs.
