In an article at Variety, the trade mentioned which company will head up the visual effects for Kenneth Branagh’s Thor:
In a second coup for France, Paris’ Buf Compagnie, a top Gallic vfx/toon house, will serve as the lead vfx house on “Thor,” channeling tax coin into the Marvel production.
The company has been in business for 25 years and some of its latest projects included Avatar, Knowing and Solomon Kane. You can learn much more at BUF’s official website where you’ll also find a video showing the company’s effects work over the years.
