Tom Hanks spent the 1980s in comedies, Splash, Big and Bachelor Party, and the pivot to drama was neither obvious nor guaranteed. Philadelphia and Forrest Gump won him consecutive Best Actor awards, which only Spencer Tracy had done.
The persona that settled is competence under pressure without complaint. Apollo 13, Saving Private Ryan, Cast Away and Captain Phillips all put an ordinary professional in an impossible position and watch him work the problem.
Cast Away is the one that shows the range, carrying nearly an hour of screen time alone with a volleyball and no dialogue.
He has directed twice, written a book of short stories about typewriters, and become the default American narrator for historical documentary, which is a role the culture assigned him and not one he sought.
