Megan Fox’s reduced presence on the big screen is due to a combination of personal choices, industry dynamics, and a shift in her career focus. After achieving fame with blockbuster hits like Transformers, Megan faced challenges stemming from her outspoken nature, which led to tensions with industry figures and a period of professional setbacks. She later chose to prioritize her personal life, including raising her three children with then-husband Brian Austin Green

Fox has also shifted her focus to roles that align more with her interests, including smaller, independent films and projects that allow her creative expression. In recent years, she has explored television appearances, modeling, and ventures like poetry, indicating a diversified career path. 

While she hasn't completely disappeared, her selective approach and preference for personal growth over relentless stardom explain why she is less frequently seen in mainstream Hollywood productions.
