French actor Vincent Cassel is linking his Sundance movie "Partisan" — about the training of child assassins — to the Charlie Hebdo terror attacks.

Cassel plays a teacher and mentor to young boys learning how to kill in the film, based on real-life reports from Colombia. He says the themes are relevant to the discussion in France in the wake of the Jan. 7 assault on the satirical newspaper.

"What just happened in France with the Charlie Hebdo thing ... the discussion right now in France is very much about education and how come kids popping out of nowhere suddenly decide to go on a jihad and kill people," Cassel said.

Cassel, who said he wasn't in Paris at the time of the attacks, stands strongly behind Charlie Hebdo's sometimes provocative philosophy.

"I personally think we should be able to make fun of anything. Anything. To make fun of things is actually a very healthy thing," Cassel said. "The minute you censor yourself, it's the end of freedom really."
