The theatre impresario is preparing to launch a U.K. show to find a new actor to play Jesus in the reboot of his hit 1970s stage spectacular.
Former Spice Girl Melanie Chisholm, who will play Mary Magdalene when the production debuts in September (12), and Aussie singer Jason Donovan have helped compile a shortlist during a rigorous audition process.
Now Harry Potter star French - who portrayed a beloved vicar in hit BBC comedy The Vicar of Dibley - has joined the judging line-up for the live shows, which will air in the U.K. over the summer (12).
In a statement, she says, "I'm gagging to find Jesus with the help of the Good Lord. I have actually been searching for him my whole life, and I can't believe that inside a few weeks we are going to find him.
"The fact that he is going to be a Rock God is a massive bonus."
