Emma Watson, Daniel Radcliffe, and Rupert Grint all became wealthy through the Harry Potter franchise, but their careers after the series have been very different.
Radcliffe pursued film, television, and especially theater, while Grint expanded into television and other projects.
Watson pursued a mixture of acting, fashion, education, activism, and business.
Comparisons between the three are therefore difficult.
More importantly, different net-worth websites produce different estimates for all three performers because none of them publicly provides a complete balance sheet.
