From the Highway - Casting

Friday was a double script meeting day. That's a little hardcore for me because I spend a lot of energy in a meeting. Each of them runs 2-4 hours. And I'm totally invested at every moment. Last meeting was with Yorgos Siougas about the "Mountain"-project. We had a good start. Some obvious chemistry and shared references. I'm curious to see where it leads. The first meeting was with Giannaris and we concluded the character-phase, where we have been going over all the characters again, this time making sure that they all reflect our basic conflict and theme. Looking at how they mirror our main character. The work has produced a lot of great details and small corrections/clarifications. And has been fun, too. Our next phase is to go scene by scene from the top. We will check each scene for a) the sharpness of the characters' objectives b) connection to central conflict/theme c) montage-value.
By montage-value I refer to the value you accumulate in the way you set the scenes up against each, the connections of relevance you make when you cut from one scene to the next. In this respect we are trying to establish some basic montage rules for the film. We are still debating them. Guess it will be our first subject for the next meeting. And then we are trying to seriously discuss potential actors, especially for the two main parts, Jason and Kate. After this cycle of improvements the script should be ready to convince top-tier actors of the projects attractiveness. And we really need to find 1 or 2 names to carry the film into the international market. Maybe you have some casting ideas? The two characters are:
Jason is his early 40s, a man with a strong body, a face that tells you of experience after 20 years sailing all over the world on the oil-tankers his adoptive family owns. He is a captain and 'a good man'. Giannaris sees Jason as a mediterranean type (dark hair, dark skin - some passion under a civilized exterior).
Kate is his wife, just a little younger than him, she is a grounded woman, who has known loss and difficulties without losing her faith in life. She can at times be cynical, but her objective is always aimed directly at enhancing life. She is trained as a medical doctor, she has good instincts and a quick mind. Guts. Physically Giannaris sees her as a more north european type.
Suggestions and comments are more than welcome. Oh, and the title is now not going to be Welcome Aboard. New title suggestion is Overboard. See the new poll.
