Jerry Bruckheimer, one of the most important producers in Hollywood, has commented in a recent statement talking about a sequel to "Top Gun":
“We tried to do the sequel and we couldn't do it. Then Tom (Cruise) took it up again some time later, although he did not eventually come out ahead. We've been talking about "Top Gun 2" again, but nothing definitive. We have come up with some ideas because aviation has completely changed since we made the first installment. So we want to find a way to stick our heads in and incorporate Maverick into those innovations. "
What is clear that with a Tom Cruise that has not been a box office success for a long time, he would be almost forced to make this sequel. And if not, time to time.
