The Canadian study showed that domestic joint ventures ranked higher in television projects than international joint ventures. However, for large budget projects, it was found that domestic joint ventures are not a viable alternative to international joint ventures.  In their subsequent study of co-production in Australia, the authors identified financial pooling as the most important benefit and increased coordination costs as the main drawback.  This indicates that co-production is more appropriate for higher-budget productions, especially for films that have higher capital needs but do not bear the same dollar-by-dollar coordination costs as smaller projects. Co-production is also about how services are produced by their users in certain parts or completely. A co-production is a joint venture between two or more different production companies for the purposes of film production, television production, video game development, etc. This does not mean that you can go your own way and change a project on which you have agreed. International film co-productions were widespread in the 50s, 60s and 70s between Italian, Spanish and French production companies, as most spaghetti western films, swords and sandals illustrate as Spanish-Italian co-productions, typically staged by an Italian, played by Spanish and Italian actors and shot in landscapes of southern Spain. Due to the worldwide popularity of Hollywood stars, they would be used to guarantee a respectable audience around the world as well as in the United States.
