The Chicken Run 2 recasts are a right shame, but unfortunately super common in animation. I can however say with confidence it was a Netflix decision, not Aardman. I don't plan to boycott the film (my stance on boycotts has always been rather simple, "if it's a quality product, support 'em") but if they don't get Julia to reprise Ginger it'll be just the slightest bit awkward of an experience. Here's a petition you can sign, if it makes waves we could brighten the future of theatrical western voice acting. https://www.change.org/p/aardman-animations-do-not-replace-julia-sawalha-for-the-chicken-run-sequel
