I recently learned about a Japanese movie called “My Dad Is A Heel Wrestler”, starring New Japan’s Hiroshi Tanahashi and a number of other current & former New Japan wrestlers (I counted at least 9-10 including Kazuchika Okada, Togi Makabe, Ryusuke Taguchi and more plus referees-note this movie was released in Japan in 2018). Thanks to the JFF Theater service, you can watch this movie FOR FREE for a limited time (until January 7, 2027) at the below link:

A JFF Theater account is required to watch, it is free and only requires a valid email address. Also, due to licensing restrictions it may not be available in some countries but it is available in the US. It is in Japanese but subtitles in many languages including English are available.
