Thomas Smith, aged 16, from Attleborough, will be starring in tonight’s episode which airs at 8.30pm alongside David Mitchell, Harry Enfield, Ben Miller and Liza Tarbuck.
Mr Smith has been acting for five years in amateur productions, both with Thetford Players and Norfolk Amateur Drama Society, but this is his first professional role.
Like his character in Upstart Crow, Rodney, a child who suffers prejudice, he has also suffered discrimination in his ambitions to be a professional actor, facing rejection when trying to join amateur groups.
But his perseverance and determination has paid off with him also filming a TV advert that will be broadcast later this year.
He dreams of becoming a professional actor when he leaves college and will be watching the episode with his family and friends at his own “premiere party” complete with red carpet and limo.
His father, Andy Smith said: “Thomas has always loved acting, but we have had to fight for Thomas to be accepted.
“When trying to enrol Thomas in drama groups, we would often find that suddenly there were no places left, phone calls were not returned or we were simply told that ‘the group is not suitable’.
