First Look- Aardman Animations Early Man
For many years, Aardman Animation were the go-to folks for stop motion animation. They were behind the original Wallace and Gromit shorts and Creatures Comforts for TV, and also had a huge hit with Chicken Run back in 2000 - still the top grossing stop-motion film of all time.
More recently they've released The Pirates! In an Adventure with Scientists and Shaun the Sheep which did pretty well last year, now their latest project is gearing up for production.
