If Tom Cruise gets his way (and we know he will), there will be no CGI fighter jets in Top Gun 2. In an interview with Extra, he stated:
“If I can figure it out, if all of us can figure it out, it’d be fun to do. I’d like to fly those jets again, but we got to do all the jets practical, no CGI. I’m saying right now, no CGI on the jets. If we can figure all that out, and the Department of Defense will allow us to do it, that would be fun.”
As Cruise in known to be an action junky, and does many of his own stunts, this makes sense he’d want to real deal. But to be honest, I doubt there is anyone in the audience who will really care, or even notice for that matter.
