Gillian Anderson is one of the world's biggest stars.
She came to huge fame as Dana Scully in X-Files back in the 90s and since the she has graced many TV shows and movies.
She even played Margaret Thatcher in The Crown and now she plays another villain in the new Aardman movie, Robin Robin.
Being a superfan of Aardman Animations it was easy for her to snap up the role of 'Cat' but had no idea she would have to sing!
(Don't worry she pulls it off brilliantly in character!)
Alison Curtis on Weekend Breakfast spoke to Gillian about the new movie, which is fabulous!
