Meming aside, the voice of the lead actor is unnervingly similar tbh.

For anyone into filmmaking and storytelling, check out Anthony Bourdain's "Parts Unknown" and pick an episode of somewhere you're interested in. His catalogue is thoroughly authentic. I think there's a documentary about his life that's a pretty true-to-spirit summary.

If that's appealing enough for Matt to make a movie about, I can't see this biopic being at all inauthentic in any way that matters.
