He’s known for being one of the nicest guys in Hollywood, but not even Tom Hanks can resist publicly poking fun at one of his good friends! During a new interview on The Late Show with Stephen Colbert, the 61-year-old actor joked his co-star Meryl Streep is quite “high maintenance!” When asked what it was like to work with the screen icon, 68, in their new movie The Post, Tom candidly replied, “You mean, can I just say, ‘high maintenance Meryl Streep?'”

“Oh really? Diva?” host Stephen Colbert pressed, to which Tom said, “Look, the shoes alone, man… No, I am so joking.” In fact, the Big star revealed Meryl actually doesn’t get any special treatment on-set despite her many years working in showbiz. “You know what’s scary about Meryl? She comes in and does it just like everybody else does. You’re expecting French horns before she enters the stage. You expect a guy in livery to come out: ‘Ladies and gentlemen, the actress known as Meryl Streep.’ And she comes in and waves to the crew the way the royals used to.”

Interestingly, The Post — which is set to hit theaters on Friday, Dec. 22 — is the first time Tom and Meryl have worked on a major motion picture together. However, the two did both appear in the 2015 documentary Everything Is Copy. Though both Tom and Meryl have reached tremendous Hollywood success over the years (he’s won two Oscars and she’s taken home three), Tom’s life hasn’t always been easy.

In his new book of short stories, Uncommon Type, Tom opened up about his difficult and unconventional childhood. “Our world did not reflect everybody else’s or what we saw on TV… By the time I was 10, I had lived in 10 different homes,” he wrote. “My siblings would say it wasn’t that fun — we were miserable. But in some ways, it was very cool because we laughed a lot.”
