Tomas (Franz Rogowski), a German man in Paris, is directing a period piece.
On set, hes a hardass, always yelling, screaming and nitpicking about small things.
Of course, this starts an argument between the two, which leads to Martin walking out.

Martin begins sleeping with Ahmad (Erwan Kepoa Fale), and when Tomas finds out, hes upset.
What did he expect Martin to do?
One thing that kept running through my head while watchingPassagesis, This movie cant be serious.

In one scene, Tomas says, Martin says I can be terribly self-involved.
Wow, no kidding.
Sachs and Zacharias script makes some odd choices.
Also, why are French people speaking English to one another?
There is a scene where Agathe is at an evening dinner speaking English.
They have a conversation about the ways in which they connect to Tomas.
Hes caused enough heartbreak, and now its time to grow up.
This character is one of the most annoying Ive encountered in a long time.
