YOKO – Based on true events – Told from Japanese artist Yoko Ono’s perspective – The story of how she and Megastar John Lennon fell in love in 1966 and the incredibly powerful forces that tried to tear them apart.

Sounds more like a concept right now. A concept that is interesting, mind you. But within an inciting incident, it's hard to imagine the story.

Instead of telling us the story is told from the point of view of Yoko, you should just write the logline from Yoko's point of view.

This would be a very poor example of a logline written from Yoko's POV: (Yours would be different and hopefully better)

"When she falls in love with John Lennon, a Japanese modern artist strives to push her love forward artistically even at the expense of the band."

Hope that helped

Once again, I point out the costly and time consuming legal hurdles that have to be cleared to make a movie about a living celebrity. ?Particularly a story like this that presumes to tell the story from her point of view, as if to know her private thoughts and feelings.

Without her legal consent and and active participation, I believe this project will be extremely difficult to launch.

fwiw

Agreed with Karel.

Of all the events that happened in their lives together which were can be used as a basis for a plot?
In other words, which of the situations they faced together gave them a goal to pursue?

It's an interesting premise, and a movie that could work. But the logline is not written in accordance with the structure we use on this site. So it's hard to say if the story would work in its own right.

Films like this attract attention because of the celebrity factor, and may work for that reason. But the the 'powerful forces' are faceless in this logline, so it is hard to visualise how this will play out, without?knowing the story of John & Yoko already.
