Nice to revive a 9-year old thread!
Came across a somewhat recent French documentary about the life and contributions of Ronny Coutteure. There's a short segment on Lucas and Young Indy. From what I could gather through the context and my limited French, it just talks about how he caught Lucas's eye, their relationship, his rise to international recognition on an American TV show, all the cool places he was able to go on Lucasfilm/ABC's dime, and, I think, how at the end of it he really wanted children(?).
could you or one of the other Francophones take a peek and see if there are any other cool details? Maybe there's something in there we didn't know already. The Young Indy bit goes from about 24:50-29:37
