"It's becoming a tradition. She had her first, one-year birthday party yesterday. And here I am today. I'm just like sort of transported," he says.
"I think it's a good tradition. We had a nice time together yesterday."
Dream Scenario is set to hit theaters on Nov. 10.
Cage, who previously shared that his little one's birthday celebration will include her wearing "a Supergirl cape," left home after the comic book festivities to promote his new film — which comes from the minds of writer-director Kristoffer Borgli and co-producer Ari Aster.
According to a summary on the TIFF website, it follows a professor who realizes that he's starting to appear in other people's dreams, making him an "overnight celebrity."
The festival, along with A24, shared a first look at the film in August, with Cage appearing unrecognizable in the role as he rocked a balding head of hair, grey beard and glasses. A24's websitealso notes that Michael Cera and Julianne Nicholson appear alongside the actor in the cast.
"I always like it when my father shows up," he says. "I haven't seen him in person since he passed on. So when he shows up, that's always a good thing."
Cage told Access Hollywood after the revelation that he was "extremely excited" to be a dad again, since his "boys" were "all grown up."
"I miss going to the toy store. I miss singing lullabies and rocking in the rocking chair," he said at the time. "I'm looking forward to getting back to that."
