Is the super mario galaxy movie based on a specific video game?

Based on the verified evidence, 'The Super Mario Bros. Movie' released in 2023 is explicitly described as being based on Nintendo's Mario video game franchise as a whole, rather than derived from any one particular game. The film adapts characters and settings common across the franchise including Mario, Luigi, Princess Peach, and Bowser, placing them in a conflict between the Mushroom Kingdom and the Dark Lands. While the movie draws from established Mario universe elements such as the brothers being plumbers and the princess-led kingdom, the source material does not specify whether it adapts storylines from particular entries like Super Mario Galaxy or other mainline titles. The distinction matters because the Mario franchise spans multiple distinct games with unique narratives, planets, and mechanics across various platforms and generations. Since the evidence only confirms adaptation from the general franchise without identifying specific source games, any connection to Super Mario Galaxy remains unverified and should be treated as uncertain rather than definitive.
