CST The Gate worked closely with Aardman studios in the filming of the ad, which features the track 'Tubthumping' by Chumbawumba.
The ad, which launched in August, features the underdog character at home with his leg in plaster and shows his struggles against his injuries as he tries to seek help.
Social media and search advertising is also central to the campaign.
During the production of the TV ad, National Accident Helpline's Facebook fans were invited to name one of the characters in the ad and the winning name features in the final ad.
Explaining some of the decisions behind the production, Gordon Smith, executive creative director of CST The Gate, said: "We chose the song tub-thumping because the lyrics fit perfectly with what we want to say. When you’ve had an accident, you want to get back on your feet, and get someone to sort out the compensation you deserve."
