Trivia

The film required 2.8 tons of Plasticine in 42 colors and 1000 baby-wipes per week to wipe it off animators' fingers.

DreamWorks wanted Aardman to replace Peter Sallis, the voice of Wallace since the first animated short, with a well-known actor that American audiences would recognize. According to Entertainment Weekly, they politely but firmly refused; instead, they got Ralph Fiennes and Helena Bonham Carter to play roles.

During filming, Aardman managed an average of 3 seconds of usable footage per day.

The film took five years to make. Production started shortly after the release of Chicken Run (2000), Aardman Studio's previous co-production with DreamWorks Animation.

The 24-carat trophy joke was a last minute addition. It was originally a silver trophy, since traditionally silver bullets kill a werewolf.
