Jean-Claude Mézières & Pierre Christin in Conversation, moderated by Paul Gravett.
The extensive and otherworldly work of Jean-Claude Mézières and Pierre Christin is one of the most influential in the whole sci-fi world as we know it. In 1967, they created the Valerian & Laureline comic book series, which tackles social and philosophical issues with a strong dose of mid-century radicalism and has just been adapted into a film by Luc Besson. They will share and discuss with the audience what makes their collaboration unique, between political commentary and colourful art.
As if that's not enough you can tie this in with the opportunity to see the recent Valerian movie - chat+movie = £15, what's not to like?
