[TOMT][MOVIE] Orphan/ lost kid roams empty streets and buildings with a bike.

Reddit watched a movie that has some lost/ orphan kid that walks empty streets/ buildings looking for food and things in a post-apocalyptic setting.

The streets/ architecture is french-looking?

At one point the kid enters an abandoned ship that where the water is dried up. And meets two guys I believe who were eating rice/ some kind of food in there.

The weather was sort of chilly/ cold if I remember correctly. I watched it between 2004-2008 if that helps. Genre perhaps is Drama, movie did not appear old at the time. Def. made after the year 2000 from the cinematography I remember.

Have looked everywhere and no luck.

EDIT: u/itsoblivia found it. It's Empire of the Sun and here's the clip I remember most about the rice: https://www.youtube.com/watch?v=pkPKjRXqVgQ

I'm beyond thankful after a very long search <3
