Did you know that one of the catchiest songs in the movie Barbie was actually a joke?

That’s right, the song “I’m Just Ken” that Ryan Gosling sings as the iconic doll’s love interest was never meant to be in the film. It was written by Mark Ronson, the Grammy-winning producer and musician who has worked with artists like Amy Winehouse, Bruno Mars and Lady Gaga.

Ronson revealed in an interview that he wrote the song as a fun exercise for his friend Greta Gerwig, who directed and co-wrote the movie. He said he wanted to capture the essence of Ken, who is often seen as a bland and boring accessory to Barbie. He recorded a demo and sent it to Gerwig, thinking she would laugh and forget about it. But to his surprise, she loved the song and thought it was perfect for the movie.

But that’s not all. When Gerwig played the song for Ryan Gosling, who plays Ken in the film, he was so impressed by it that he insisted on making it a musical number. He said he felt that the song added depth and humor to Ken’s character, and that it was a great way to show his feelings for Barbie. He also praised Ronson’s lyrics and melody, saying they were catchy and clever.

Ronson said he was amazed by how much Gosling’s interpretation of the song improved upon his original intent. He said he never expected the song to be in the film, let alone become one of its highlights. He also said he was honored to work with Gerwig and Gosling, who are both talented and visionary artists.

The song “I’m Just Ken” is one of the many reasons why Barbie is such a fun and fresh movie. It shows how a simple joke can turn into a brilliant musical moment, thanks to the creativity and collaboration of talented people. If you haven’t seen the movie yet, you should definitely check it out. And if you have, you can listen to the song again on Spotify or YouTube. Trust me, you won’t regret it.
