Ben Affleck wins the top prize during a celebrity guest appearance on the TV game show “Who Wants To Be A Millionaire,” according to reports by two outlets. Both sources say Affleck takes part in the episode this week and ultimately lands the rare $1,000,000 prize. The articles describe the win as a high-value outcome that is not frequently awarded on the program, emphasizing that the $1 million prize is considered rare. Aside from the win itself, the provided summaries do not include additional details about the specific question Affleck answered, the contestants involved, or the broader episode context. The reporting is consistent in stating the show title, the timing (“this week”), and the prize amount ($1 million).
