Taking the top movies in adjusted domestic gross, dividing by their non-adjusted domestic gross, and then multiplying that ratio by their worldwide gross, you get:<p>1. Gone with the Wind - $3.04 billion
2. Titanic - $2.34 billion
3. A New Hope - $2.24 billion
4. E.T. - $1.93 billion
5. The Sound of Music - $1.92 billion
6. Jaws - $1.73 billion<p>As of this post, Avatar is 2.05 billion and climbing. Will it be the most watched movie of all time worldwide (in theaters), or will Gone with the Wind retain its dominance? *Data taken from boxofficemojo.com.
