why did they change the actor for asterix in this new film?
it looks strange with a NEW asterix

Gérard Depardieu has a magnificent nose.

Because maybe Christian Clavier did not want to return for a third one?

yes but why? is he sick
he have not done any movie or tvshows since 2k5
maybe Depardieu/or some one else on the team have some sort of argument...more money? more spotlight?
...
lol
is there an official reason why
thats all

French wikipedia merely states he refused to reprise the role.
My guess is he doesn't want to be typecast.
