Actor Charlie Hunnam broke down in tears as he shot his final Sons Of Anarchy scenes with his onscreen mother Katey Sagal after having to kill her character on Tv.

The Pacific Rim star portrays motorcycle gang member Jax on the hit series, and he had to shoot Sagal's character Gemma in the penultimate episode of the seventh and final season of the show, which aired in the U.S. at the start of the month (Dec14).

Sagal recalls the scene was so tough for both actors as they had worked together for seven years on the drama.

Sagal tells People magazine, "It was very emotional in a beautiful way. Charlie Hunnam and I cried a lot. We would just hug each other because it was also goodbye for us after working together. We've all been in our own form of denial with the show ending. But there was no turning back."
