I remember this movie I watched on the 90’s.

It is a color movie with french speaking actors.

The main character begins the movie talking in a public phone, when an old man answers on the other side of the phone, the main character grabs a revolver, shoots through the phone and kills the old man.

The main character used to live with his father and he is very afraid of drilling machines near his house. I think he is somehow close to monkeys.

The main character also meets a chubby woman that because of stress (when they’re been chased by some bad people) losses a lot of weight. She is then able to pass through a hole in a wall.

I appreciate all the help,

Thanks!
