Headscratchers / Les Visiteurs

• How can Jacquouille recover the jewels in the future, since that future was created with the assumption that Godefroy and Frénégonde would get married, meaning her father hadn't died at the hands of Godefroy?
• In Bastille Day, during the last sequences, we meet Jacques-Henri Jacquart in 1943, who seems to be about ten. However, in the first movie, set in 1992 (as evidenced by the scene with the calendar) he sure doesn't look like he's sixty.
