He was hospitalized weeks after fans expressed concern over his skeletal appearance. His drastic weight loss was explained away as weight loss for a movie role.

In 2018, Boseman became emotional when discussing his visit with two young fans who died of cancer before Black Panther was released.

"Throughout our filming, I was communicating with them, knowing they were both terminal. What they and their parents said to me was, they were trying to hold on 'til this movie comes," he said during an EW SiriusXM Town Hall.

"To a certain degree it's a humbling experience because you're like, this can't mean that much to them," he said. "But seeing how the world has taken this on, I realize they anticipated something great. Thinking back now to when I was a kid, waiting for Christmas to come, waiting for my birthday to come, waiting for a toy I was gonna get a chance to experience, or a video game, I did live life waiting for those moments. It put me back in the mind of being a kid and feeling those two boys' anticipation of this movie."
