SAN DIEGO: Tom Cruise has made an unexpected flyby at San Diego Comic-Con to debut the first trailer for “Top Gun: Maverick.” The audience in the 8,000 seat room went wild for Cruise Thursday afternoon. He closed out what had been billed only as a panel for “Terminator: Dark Fate.” Cruise says all the flying in the trailer is real and that “Top Gun: Maverick” is a love letter to aviation. They worked with the Navy for the film, which is currently in production. “Top Gun: Maverick” is expected to hit theatres next June. Val Kilmer, Jon Hamm and Miles Teller co-star. Cruise said Comic-Con was the perfect place to premiere the trailer. He shot the original some 34 years ago in San Diego.
