I’m pretty sure it was a French film from early 2000s but possibly earlier. I haven’t seen it for 15 years but this is what I remember.

The main characters are former child actors down on their luck. They hatch some scheme whereby they plan to sell a teen girl, posing as their daughter, into prostitution but at the last minute can’t go through with it. So then they have the pimp chasing them. Eventually they head for Spain.

It was a comedy. I’ve spent years trying to find it. I vaguely recall marionettes used in the opening scene. Please help!
