What was the reason that SeaWorld filed a complaint with the Department of Labor against an OSHA worker ?
The inclusion of a SeaWorld video of a female trainer riding a killer whale , while one of the cast members , Samantha Berg , talks about her experience at Shamu Stadium , pointing out that the segment implies that Berg had relevant experience when the video used in the film was actually shot 10 years " after " Berg had left SeaWorld ( The trainer depicted in the video is not Berg but rather a current SeaWorld employee at the time of " Blackfish " 's production ) .
