In films, an executive producer finances the film or participates in the creative effort, but does not work on the set. His/her responsibilities vary from funding or attracting investors into the movie project to legal, scripting, marketing, advisory and supervising capacities.
The crediting of executive producers in the film industry has risen over time. In the mid-to-late 1990s, there were an average of just under two executive producers per film. In 2000, the number jumped to 2.5 (more than the number of standard 'producers'). In 2013, there were an average of 4.4 executive producers per film, compared with 3.2 producers. (Wikipedia)
