The 5 Harry Potter movies to date have to date grossed $4,453,611,811. With the next in the series out in 2009 (Harry Potter and the Half-Blood Prince) he will probably become the first actor to gross over $5 billion. By the time the next two follow in 2010 and 2011 he should be around the $7 billion mark.
If, for some reason, you exclude Daniel then the previous answer (below) may be what you are looking for:
As of Feb 2009, the total is now $8.6 billion worldwide
Followed by:
Harrison Ford: $3,279,246,253
Tom Hanks: $3,093,654,701
What About Sir Ian McKellen, who has been one of the primary characters in the LOTR and X-men trilogy? Combine them both and you get over $4 billion.
The Radcliffe & McKellen numbers are world-wide, while the others are US Domestic. See http://www.the-numbers.com/people/. World-wide, Tom Hanks and Samuel Jackson are already over $7 and 8 billion, with Frank Wekler over $9 billion.
I just wacked it to "The Long Kiss Goodnight".
