Being Batman is a seven minute documentary film by Lossless Creative that puts the camera on a real life Batman. The level of dedication of this person is really compelling and the film weaves Batmans words and life together in a really beautiful way. I wouldn't really call this cosplay but a person with an intense focus on Batman such that he has become him.

Interested to have you watch this and then let me know what you think of it in the comments.
