THE Chase star Anne Hegerty was cast on the show after fighting off a gang of muggers, TV boss Sue Allison has revealed.
The brainbox has been a Chaser on Bradley Walsh's gameshow since 2010.

And Anne caught their attention after writing a letter to bosses telling them she was tough as nails, as well as smart.

"There were really good quizzers on the circuit, that was the most important thing first and foremost. The people that we met were quite often great quizzers but they were just a bit too nice.
"When we got a letter from Anne, she wrote into the team and said something like she 'realised what kind of character you needed to be' because she'd seen the pilot series.
"And she realised you needed to be quite tough, and she had once chased off a couple of muggers.
"I remember getting this letter and thinking, 'come on, be as good as you sound' and she was."

"So I remember the day our wardrobe designer took her off to the shops to find something.
"Then this picture comes back of her looking like Ms Trunchball, and it was like yes, that's the one. She has been a genius from the start.
"She just got it. She's actually a brilliant actress and she delivers those lines so perfectly when she comes out. Her comic timing is absolutely spot on."
