Ryan Reynolds is traveling back in time to reminisce about making one of his favorite movies yet.

The Golden Globe nominee, 46, said working on Netflix's The Adam Project "was unspeakably fun" as he marked one year since the premiere of his time-travel film in a sweet tribute he shared Saturday on Instagram.

"One year ago today, #TheAdamProject came out on @netflixfilm," he started in the caption. "Or as it's more commonly known, 14 Going On 31."

"I love this movie because it feels like the kind of film I grew up with. The kind of film that made me dream of doing this job," he continued. "Working with this incredible cast was unspeakably fun. I'm already on my third film with the great, @slevydirect and I know I speak for both of us when I say this film holds a soft spot in our hearts forever."

He and director Shawn Levy previously worked together on 2021's Free Guy, and they're currently filming Deadpool 3.

Reynolds also noted that The Adam Project served as the "inaugural voyage" for Group Effort Initiative, which provides a pipeline to lasting careers in the film industry for underrepresented communities, and has "grown into a beast since then."

Jennifer Garner, who starred as Reynolds' mother in the movie, dropped a laughing emoji in the comments at the "14 Going on 31" joke after her 13 Going on 30 reunion with costar Mark Ruffalo. "The best movie experience ever," she wrote.

In The Adam Project, Reynolds plays time-traveling fighter pilot Adam Reed, who crash lands in 2022 and has to team up with his 12-year-old self (Walker Scobell) to save the future.
