Mark Wahlberg poses as a pilot with sinister motives in the trailer for Flight Watch with Michelle Dockery and Topher Grace directed by Mel Gibson

Mark Wahlberg plays the pilot of a single-propeller plane, who is not who he appears to be in the first trailer for Flight Watch.

Wahlberg, 53, plays a pilot hired to pilot a U.S. Marshal Harris (Michelle Dockery) and a witness (Topher Grace) assigned to testify against the Moretti crime family.

What neither the Marshal nor the witness initially realize is that the pilot is not who he says he is. Ultimately, he turns out to be a hitman for the Moretti family.

Lionsgate announced in May that the film – directed by Mel Gibson – had an October 18 release date, putting it up against Paramount’s Smile 2 and Searchlight Pictures’ A Real Pain starring Kieran Culkin and Jesse Eisenberg.

The trailer begins with the pilot saying, “Deputy Harris, I hope you enjoy flying, have a nice day,” as he is seen flipping several switches in the cockpit.

‘I’ve never flown with a US Marshal. Why is he all chained up?’ the pilot asks as Harris responds, “I need to get him to New York so he can testify against the Moretti crime family.”

They show photos of the witness in a suit, talking to top members of the mafia family, as the pilot says, “Okay, hey, you’re the boss.”

The single-propeller plane takes off and flies over the snow-capped mountains when some turbulence occurs.

“Is it always this bumpy?” Harris asks, as the pilot jokes. “You know how many passengers have lost their lunches here, I could open a snack bar.”

Harris notices a scratch on the pilot’s neck and asks if he’s okay. He waves it off, saying, “Ah, maintenance. Occupational hazard.”

However, he turns around and she sees a small bloodstain the size of a bullet on his long-sleeved shirt… while the witness sees the pilot’s license of a man named Daryl Booth… but the photo doesn’t match the pilot.

Harris tries to point her gun at the pilot, but he stops her. A struggle ensues and he pulls out a knife.

“Mr. Moretti is very disappointed in you, Winston, and he wants you dead,” the pilot says, as Harris pulls out a stun gun and shocks the pilot with it, his baseball cap coming off and revealing his bald head.

“Mr. Moretti is very disappointed in you, Winston, and he wants you dead,” the pilot says as Harris pulls out a tranquilizer gun and shocks the pilot with it, his baseball cap coming off to reveal his balding head.

Harris sends out a distress call saying, “We have been compromised. The pilot is an assassin.”

“You’re clearly confusing me with someone who really cares,” the pilot says, as he sees a military plane flying next to his plane

Harris eventually gains the upper hand on the pilot and ties him up, pointing her gun at him as witness Winston says, “Don’t shoot him! We need him!”

Harris sends out a distress call saying, “We have been compromised. The pilot is a hitman.’

The pilot/assassin says, “I’m going to tear you into little pieces,” as a knife falls on him as he stabs Winston in the shoulder.

“They’ll need a whole forensics team to identify you,” the hitman continues as they show a fight ensuing with a fire extinguisher.

Harris tells the pilot, “Tell me how to fly this thing. Otherwise we’ll all die here,” although the pilot isn’t bothered.

“You’re clearly confusing me with someone who actually cares,” the pilot says, as they see a military plane next to their plane.

“Do you think it’s here to help? It’s there to shoot you,” the pilot says as they show a series of quickly edited dramatic shots.

One such shot shows the plane going into a nosedive as Winston tells Harris to take off, as she does, and we see the plane emerge from the snow.

“Y’all need a pilot?” the pilot says in his fake Southern accent as he’s strapped in, as the trailer comes to a stop.
