Update: It seems UK's The Guardian became aware of Frank Welker's unofficial status as Hollywood's top earner. Also The Numbers site has a new chart that breaks down the totals but oddly most are half the size they use to be so not really sure what changed from the chart below to the new one. Still Welker remains top dog at $6.2 billion followed by Samuel L Jackson ($5.2B), Tom Hanks ($4.4B), John Ratzenberger ($3.9B) and Harrison Ford ($3.7B).
Flickering Myth discovered an interesting stat on The Numbers.com. Transformers' Frank Welker is the highest grossing movie star ever with a total gross of about $12.5 billion. This is based on the total movie worldwide box office gross of movie actors, regardless of the size of their role in a film. This large total is despite most of his voice work being for television with the Transformers movie franchise (as Megatron) accounting for about 40% of that total. The next four top actors are Samuel Jackson ($10.15B, thanks to Marvel movies), Warwick Davis ($9.7B, mostly due to Harry Potter), Tom Hanks ($9.16B due to his legendary film career), and John Ratzenberger ($8.3B, mostly due to all the Pixar love).
Mr. Welker's other movie voice credits include Indiana Jones and the Raiders of the Lost Ark, Who Framed Roger Rabbit (Dumbo, others), Caddyshack II (the Gopher), All Dogs Go To Heaven (Devil Dog), Gremlins 2 (Mohawk), A Bug's Life (Thumper), Toy Story 2 (Bullseye), How the Grinch Stole Christmas (Max the Dog), and many more. If you have never read his credits you really should give them a pass at it is truly amazing just how many childhood favorite shows and characters he has lent his voice too over his 40+ years long career. He probably has had more of impact on people's childhood then most people are even aware and really is deserving of more credit than the Hollywood establishment gives him and other voice actors.
