* Box Office: If we look at pure box office gross, "Toy Story 4" (2019) would be the winner, with over $1.07 billion worldwide. However, Hanks was only the voice of Woody, not the main star.
* Critical Acclaim: "Saving Private Ryan" (1998) and "Philadelphia" (1993) are both critically acclaimed movies that earned Hanks numerous accolades, including Academy Awards.
* Cultural Impact: "Forrest Gump" (1994) is widely considered a cultural phenomenon, winning six Academy Awards and leaving a lasting impact on the film industry and American culture.
Ultimately, "Forrest Gump" is often cited as Tom Hanks's most successful movie because of its combination of box office success, critical acclaim, and cultural impact.
