Here's the synopsis as taken from /film:
Since ancient times, stories of epic battles and mystical legends have been passed through the generations across the rugged and mysterious Highlands of Scotland. In “Brave,” a new tale joins the lore when the courageous Merida (voice of Kelly Macdonald) confronts
A new trailer has been released for Pixar's upcoming film Brave.
From an animation standpoint, the thing that particularly stood out to me is Merida's hair. Disney's Tangled has done straight hair really well in 3D but never have we seen curly hair done this well. The hair to me seems like a mix of complex physics based stuff and some careful manipulation to give it an exaggerated "larger than life"quality.
As for the film itself, it hard to tell what to think from this trailer. A lot of it looks really promising but the humor looks pretty goofy. However, Pixar trailers usually aren't a good representation of the actual films, as they tend to cater to young children. That said, I'm excited to see Pixar tackle a medieval setting, and links to Scottish folklore set it apart from other "sword and sorcery" family films like How to Train your Dragon.
