Just got through watching ASTERIX AND OBELIX TAKE ON CAESAR (1999), with
Christian Clavier as Asterix and Gerard Depardieu as Obelix. It's a live action adaption of some the Asterix & Obelix comics by Renรฉ Goscinny and Albert Uderzo. Yes, it's a comic book movie, just one that few of us have ever heard of.
Without being too spoilerish the plot revolves around the adventures of our two Gauls defending their village from the Romans. From what little of the albums I have read (a couple, years ago), the movie seems to capture their tone and heart quite well. There's violence, but it's all very cartoony and mostly good natured.
Clavier and Depardieu both nail their roles, though Depardieu's over-grown, superhuman, man-child shines brightest. All the comic's characters are given some screen time so you can point at the screen and go "hey, there's so & so"!
I don't know how many live action adaptions of euro-comics there have been (the only ones I can think of off the top of my are BARBARELLA and DANGER: DIABOLIK, both quite good). This has certainly got to be one of the better ones, too.
