Harry and his mates have taken a whopping £649m ($926m) from movie-going muggles worldwide.
Since it came out in 1997, Titanic has sunk a gigantic £1.3bn ($1.8bn) at the box office.
Meanwhile, the Fellowship of the Ring, the first in the Lord of the Rings trilogy, is in the all-time top 10 film chart.
But its total worldwide takings still trail behind Harry Potter at £175m ($250m).
Harry's only been out for three months though and there's still loads more money to be made out of the DVD and video sales, due out in the summer.
