Vin Diesel's Limitless Instagram Account

I don't know a lot about Vin Diesel, but he seems like a nice weird guy. And you see that weirdness in something like this. I think Chronicles of Riddick is a product and part of his interests and his desire to see some sort of fantasy epic come to life. He's on the gram. What's he doing on there? It's just a pure expression of his hopes, dreams and mind.
