This Saturday, when they answer us by phone, Grégoire Champion and Benjamin Gaitet are lounging near the Pont du Diable, in Thueyts (Ardèche). “We’re going to swim a bit because it’s super hot,” they admit. An idyllic setting, but the two actors from “Tomorrow belongs to us”, on TF 1, however, do not spend their holidays in 5-star hotels. This summer, they embarked on a hitchhiking trip for thirty days, “Beijing Express” style.
