Is there a more overrated filmography than that of Tom Hanks? Guy hasn't had a hit or a great movie in like a decade, and his crowing achievement (Forrest Gump) is massively overrated.
Well, it depends based on how you think his work the past decade is creatively. I haven't seen much of it. IMO, the best 8-year stretch from him was 1992-2000 (League of Their Own, Sleepless in Seattle, Philadelphia, Forrest Gump, Apollo 13, Toy Story, That Thing You Do, Saving Private Ryan, You've Got Mail, Toy Story 2, The Green Mile and Castaway).
As for business, the guy is money. Practically every film he's been a main star in the past decade has made money or been a blockbuster.
Road to Perdition (made $180 million+)
Catch Me If You Can (made $350 million+)
The Terminal (made $200 million+)
The Ladykillers (made $75 million+)
The Polar Express (made $300 million+)
The DaVinci Code (made $750 million+)
Charlie Wilson's War (made $115 million+)
Angels & Demons (made $480 million+)
Toy Story 3 (made over $1 billion)
Larry Crowne (made $68 million)
Extremely Loud (made $47 million to date)
Not the best quality of movies on that list (aside from Toy Story 3….I've heard the Catch Me If You Can one was good) though.
