He may be one of the biggest names at the box office, but Tom Hanks isn't forgetting what got him there.

While making the rounds promoting his latest movie "Inferno," based on Dan Brown's book of the same name, Hanks has paid homage to his movie "Big," not once but twice recently.

First, Hanks didn't miss a beat when he performed the rap from the 1988 flick.

The song appeared in the movie to help prove to his best friend that he was a 13-year-old in the body of a 30-year-old.

Nearly 30 years later, Hanks was able to recite the entire rap, but luckily he knew the song before the film was made, "The Today Show" reported.

"I actually stole that from my kid's summer camp," Hanks said.

But that wasn't the only nod to his big screen past that Hanks made this week.

On Monday night's "Late Show," Stephen Colbert appeared as Zoltar, the future-predicting midway game at the center of the "Big" story.

This time Hanks wants to regress from a 60-year-old man in a 30-year-old's body.

He says he heard his hip pop when he tried to re-create the floor piano, "Chopsticks" scene in the clip.

Hanks actually did recently recreate that scene on a British talk show. But there is no word if he did pop his hip when he re-created the scene.
