Improvement of first model
We recomputed the box-office, but this time only against thevariables that were significant i.e. budget, critics tomato, europe,
length, r, saga, supporting and trailers.

Rentability
We created a second model, this time in order to study therentability, which is the ratio between the box-office and the
budget.

Comparison of the models 1 : Batman vs Superman
First models
Box-office prediction = $263,781,100Ratio : 0.82 (adjusted R2 : 0.734)
Box-office prediction = $296,722,240Ratio : 0.92 (adjusted R2 : 0.735)
Second models
Rentability prediction = 217.43, ratio : 168.55Rentability prediction = 40.68, ratio :31.5
Pretty bad modelization of rentability.
