"I will be washing Tom's car [and] doing everything that I can to get him in that movie!" Tatum told ET's Angelique Jackson at the Fulfillment Fund gala at Universal Studios in Los Angeles on Wednesday.
Tatum admitted that he and Bell have thus far been "too afraid" to talk with Hanks about the remake, because for years their idea for the film was just a joke that they threw out to Disney as a "shot in the dark."
Tatum said he and Bell threw "a hail Mary" just to see how it would be received, and spoke with filmmaker Ron Howard, who directed the original, who ended up supporting the project.
"We were sure he was going to say no," Tatum shared. "[But] Ron loved it and supported us going in to Disney."
"We were sure they were gonna say no," he added. "Disney somehow thought that it was not a horrible idea so we’re gonna give it a shot."
While there's a lot of pressure when it comes to remaking an iconic comedy classic, it's not nearly as much pressure as choosing an educational path for your child, which is another challenge Tatum is currently facing with his 3-year-old daughter, Everly.
"Now days especially in Los Angeles there's all this pressure. She's not even in elementary school yet and there's the, 'What school is she in? What's the plan? What's the path?' and I'm like, 'I have no idea,'" said Tatum, who shares his little girl with wife Jenna Dewan. "Like, I just want her to enjoy going to school. I just want her to want to go to school."
