Avatar – (Round $237 Million)
You may be surprised to know that Avatar was supposed to be released in 1999 just after the release of Titanic by James Cameron but it released in 2009 only. The main reason for this whooping 10 years delay was the under-development of computers and technology due to which Cameron decided to hold to correctly produce his vision. The jaw dropping filming techniques and graphics sued in this film were the reason behind high production costs for this film. Likewise, Cameron had to hire Mr. Paul Frommer to develop a new language in the film. Last but not the least, Avatar brought in $2,782,275,172 at the box office and this is considered a great success.
