First French Film you Heard of or Seen

The first French film I heard of was Les Visiteurs, after I looked up info about the main actor Jean Reno after I saw him in Leon the Professional. This movie and the sequel, and the American remake called Just Visiting, and I am having a hard time trying to find copies of those 3 films. Also does anybody know where I can find copies of these three Live action Astérix films

1999 – Asterix and Obelix Take on Caesar (Astérix et Obélix contre César)

2002 – Asterix & Obelix: Mission Cleopatra (Astérix & Obélix: Mission Cléopâtre)

2008 – Asterix at the Olympic Games (Astérix aux Jeux Olympiques), because I saw trailer for them on youtube. Any help is appreciated.
