Levine also contributed the song "Go Now" to the soundtrack of Carney's latest, critically acclaimed picture Sing Street and Carney said the pair plans to collaborate on another project some time in the near future.
"Adam became a really good friend after Begin Again and we're threatening to work on something much bigger together, with him sort of, you know, acting in a big part in it," Carney told UPI in a recent phone interview. "That has been the really exciting thing from Begin Again. Obviously, I'm great friends with Mark Ruffalo now and James Corden, as well, but there is a certain sort of musical star quality to what Adam does that I am very interested in and we might jump into something together fairly soon. I hope."
Pressed for details, Carney would only say the project is still in the planning stages.
"I've been mapping something out, just trying to figure out a way of sort of getting it done," he said. "It'll be a question of can we raise the finance and how we do it and we want to sort of keep it small. But it's very, very early days."
Starring Ferdia Walsh-Peelo, Lucy Boynton, Maria Doyle Kennedy, Aidan Gillen, Jack Reynor and Kelly Thornton, Sing Street is in theaters now. Set in 1980s Dublin, the movie is about a teen who starts a band at his new school to impress his dream girl, while his home life is falling apart.
