Have you seen the first fiction films by the Dardennes? No? I have!
It's instructive to note that the brothers didn't spring fully formed from Zeus' head like Athena did. These early films are not of the same quality as "La Promesse" (1996) and everything that followed.
"Falsch" (1986) is a campy spoof, and unrecognizable as theirs. I found it unwatchable. A similar short, "The World's Racing" (1987) is kind of fun, but still, unrecognizable.
"You're on My Mind" (1992) follows the downward spiral of a steel worker after he's been laid off, and the effect on his family. It is clearly an antecedent to their later work, but a bit amateur.
