That was really fun! I haven't finished it yet, but I still think Fillion could play a great Drake in a film. I don't see why we can't have a movie starring an older Drake, that takes place after the events of the games. I don't need a movie version of the stories of the games we've gotten, although, with all of the de-aging tech we have, I wouldn't mind a few flashback sequences to Drake's Fortune, Among Thieves, Drake's Deception, or A Thieve's End.
I'm just over all of these "How they came to be," origin stories for established characters. There's nothing wrong with those stories, I'm just personally at my fill of them.
This video also made me really want a light hearted Uncharted TV series with Fillion. Do an 8 Episode season, with each one him going after some historical McGuffin. A two or three season run would be enough. Just seeing him play Nate in this video was enough to scratch my Fillion as Drake dream casting, but I wouldn't be against something official from Sony.
