I am collecting data for a statistical project I am currently working on. One of the goals is trying to find the ratio of budget/revenue for films. I have noticed that some films have their budgets listed as 0 (such as the 2017 movie "XX") while on sites such as wikipedia it is reported to be $2,000,000 and on others the revenue number is also incorrect, such as on the 2007 film "Triangle", which TMDB has reported to be $260 when wikipedia says $1,300,000 - $1,600,000. Am I using the API incorrectly or is this an actual issue? I have pulled all the films from 1980 to 2018 and there are 3251 films where either their revenue or their budget is 0 and while for some it may be the case I do not think it would be the case for approx. 1/2 the movies from 1980-2018.
