As an AI language model, I don't have real-time access to specific information such as the cast of commercials that aired in 2023. However, I can provide some general information about the Michelob Ultra Super Bowl commercials and the potential actresses who might have appeared in them.
The Michelob Ultra Super Bowl commercials have a history of featuring well-known celebrities, athletes, and public figures. In the past, they have collaborated with popular stars like Serena Williams, Jimmy Fallon, Chris Pratt, and many others. These commercials often showcase a healthy and active lifestyle, promoting Michelob Ultra's low-calorie and light beer options.
If Serena Williams, a renowned tennis player and a fan of the TV show Succession, were to appear in a Michelob Ultra commercial alongside actor Brian Cox, it would certainly be an exciting collaboration. Serena Williams is not only known for her incredible tennis skills but also for her charismatic and engaging personality. This would make her a great fit for a Super Bowl commercial, which aims to capture the attention of millions of viewers.
It's worth mentioning that the cast of Super Bowl commercials can vary from year to year, and sometimes surprise appearances are made by unexpected celebrities. Therefore, without specific information about the 2023 Michelob Ultra Super Bowl commercial, it's difficult to provide an accurate answer regarding the actress who appeared in it.
While I cannot provide a specific answer about the actress in the 2023 Michelob Ultra Super Bowl commercial, the collaboration between Serena Williams and Brian Cox would undoubtedly create a lot of buzz and excitement among fans of both the show Succession and tennis enthusiasts.
