Gosling, who is also a producer on the movie, shared that he and Mendes 'always want to find films that we can bring our kids to and have that core memory moment, but they're hard to find. I felt like, OK, well, we might just have to make it.'

Now Gosling has shared that one of his daughters helped persuade him to wear spectacles in the movie, in an interview with USA Today.
'When I was playing with the character, just trying stuff out, and I threw on some glasses, my daughter went: "You look smarter with glasses,"' he recalled.

His children have 'seen many cuts, and they've given many notes,' Gosling explained, noting that Esmeralda and Amada are 'the harshest critics, but they are always right, for the most part, and they've really been so helpful.'
