Los Angeles: Hollywood's star couple Angelina Jolie and Brad Pitt will be seen in 'By the Sea', that focuses on the thin line between love and hate, and the actress says relationships go through extreme emotions.
The 40-year-old actress-director, who has six kids with Pitt, feels one can love the person they want to kill, reported Us magazine.
"Everybody knows that there is never just the tragedy of life or the humour of life or pure joy of life. Relationships have those extremes. You can absolutely madly love the same person you want to kill," Jolie said.
"It's the puzzle of figuring out those things that get in the way of really loving someone. A lot of it's the past, a lot of it's insecurities, a lot of it's wanting something so much that you focus too much on losing it," Pitt, 51 added.
Written and directed by Jolie, 'By the Sea' is a romantic drama about a couple in the 1970s who are struggling to save their marriage.
The film also marks the couple's first project together after 'Mr and Mrs Smith,' that released in 2005.
