I am struggling with a film name. Please help :)

Dear friends,
I need your help. I was looking this film during a flight. It was particularly meaningful for me and I did stop it because I wanted to share it with an important person. Problem is I can’t remember the name …
The plot is about a astrophysics guy who has lost is wife and who do not trust love anymore. Then he meet a lively dancer who help him finding new abitabile planets.

I remember that the name of the film is “her” name.

Please help help me. I would really appreciate!!
Thanks
Marco
