Wallace and Gromit creators Aardman Animations and US studio Dreamworks have ended a five-film deal early after two movies reportedly underperformed.
Losses were reported for their last two films, Flushed Away and Wallace & Gromit: The Curse of the Were-Rabbit.
The companies have released three films together, also including Chicken Run. Dreamworks said the firms now had "different business goals", while Bristol-based Aardman Animations said their "ambitions have moved apart".
Aardman spokesman Arthur Sheriff said the separation was a result of Dreamworks' move to focus on computer animation.
The UK animators wanted to continue making their distinctive "claymations", he said.
"We always knew that America would be a hard task for us - we're a very English company," he added. "We embrace the international market but we think part of our strength is our English sense of humour and we want to continue with that."
I thought the Were-Rabbit one was a bit uncompromisingly English, which was presumably the problem. But Nick Park and co just aren’t Hollywood types.
