"They're assembling the amusement park rides even as we speak," Hanks joked with ET's Carly Steel at the New York premiere of his new film, Sully, on Tuesday.
Hanks was joined on the red carpet by Wilson, who turns 60 in October, and he couldn't have been more loving. "Boy are you going to have a [great] 39th birthday, my love."
In his new film, the 60-year-old superstar plays real-life hero pilot Chesley "Sully" Sullenberger, who famously executed an emergency landing of a commercial jet in the Hudson River on Jan. 15, 2009.
Despite the harrowing nature of the ordeal depicted in the film, Hanks says he's not afraid of flying, and even likes a little excitement in the air.
"I like it bumpy up there. I like it to be wobbly," Hanks quipped. "I say, 'Come on, fly through the clouds. Let's go. Let's make it happen!'"
Wilson, however, disagreed. "The only thing I like bouncy is my hair," she said. "I do not like it."
While Hanks wants to have a big celebration for Wilson's big b-day, the star didn't seem to want a big hullabaloo when it came to his own 60th when ET caught up with him at the Tribecca Film Fest in April.
"I grew up having my birthdays in the summertime where everybody is dispersed," Hanks, who turned 60 in July, told ET. "The day will go by with a little bit of a nod and maybe a delightful can of beer." Check out the video below to hear more from the lovable Oscar winner.
