Colin Jost has Greg Berlanti to thank for his cameo in “Fly Me to the Moon”, not wife Scarlett Johansson

"That's my fault," says the director of casting Jost, who is featured as one of the senators NASA needs to convince to vote yes on a funding bill.

Greg Berlanti might be Colin Jost's biggest fan.

The director brought Jost on to cameo in Fly Me to the Moon, as one of three senators that PR guru Kelly Jones (Scarlett Johansson) and Cole Davis (Channing Tatum) need to convince to vote yes on a funding bill that will allow the Apollo 11 mission to go forward.

One might reasonably think it was Johansson who encouraged Jost, her husband since 2020, to take part in the film (she even joked about having him appear in all her films being part of her prenup on The Tonight Show). But it was actually Berlanti, who, as the film's director, saw the opportunity to keep audience engagement high with these key small roles.

"That's my fault," Berlanti says of Jost's cameo. "[Scarlett] should get no blame or credit, but she was willing to go along with it and gave me a hard time about it in a funny way."

"When you've got these massive stars like Scarlett and Channing, when you talk to any old day player, it's hard with rockets going off and movie stars to keep the audience's interest," he continues. "You really want to make sure that even those little moments have something special about them. So, I asked Colin, and he came in and he had everybody crack up for about a half day."

In fact, Berlanti says Jost improvised so much material that he could have created quite a lengthy scene with all of it. (Deleted scenes in the future, pretty please?)

"There's just so much material I could have used," he notes. "Same thing for Jim Rash, same thing for Ray Romano. There's so much they just would do offhand that I was like, 'Oh my God, I could add a whole other hour to this movie.' That wouldn't be good for any of us, but it'd be very funny."

Fly Me to the Moon is in theaters now.
