Who said that the box office was dead? Well Warner Bros. are set to make $4bn this year in Box Office takings, the highest a studio has ever made in a calendar year.

The big films which helped Warners hit this target were harry Potter and the Half Blood Prince, their highest grosser this year, The Hangover, Yes Man, The Curious Case Of Benjamin Button and Gran Torino which all came in over $100m in worldwide grosses.

Other films which have helped are Watchmen, Terminator Salvation and The Blind Side which is yet to see a UK release but did big business in the US. Sherlock Holmes is also sure to make big money for Warners which came out over the Christmas holiday break.

Sure ticket prices are higher today than they have ever been, but we have home cinema systems today which are more affordable than ever and make staying in and watching a video a better experience than ever, couple this with the ever growing Blu-ray and video on demand market and it's a real challenge for the multiplexes.

Looking at the top earners of recent years though and they are all films which are better experienced on a large screen rather than you���re at home 50 inch plasma. Except for last year���s top film, Mamma Mia, which for some reason took on a life of its own?
