How Is A Documentary Like A Research Paper?

When you go to a dictionary to find the definition of documentary it says that the word describes a program that can be shown in film format, television or in radio and the program is aimed to provide the facts only but for representational purpose it uses actors to represent the characters.
      
A research paper is a written document that is written after doing a lot of research on particular subject and it is presented well for the people who are interested in the subject.
     
Both a documentary and a research paper do not involve any fictional topic in their content so we can compare them as equal and we can say that a documentary is a research material presented in film format to make it accessible even to those who do not want to make effort to read.
