The actor was delivering a passionate speech in his role as the famed 19th century American civil rights lawyer Clarence Darrow when the phone went off.

After the guilty owner let it continue ringing, Spacey delivered a warning while keeping in character: “If you don’t answer that, I will!”

As Lester Burnham would say – don’t interrupt him, honey.

This is the third time Spacey has stepped into Darrow’s shoes. The first was 22 years ago for PBS film Darrow and the second was in the Old Vic play Inherit the Wind.

This new performance commemorates the end of Spacey’s decade-long run as artistic director of the Old Vic.

“Wanting to get up on my beloved Old Vic stage in our 10th anniversary season was important to me. And taking on a play that I feel very close to seems right,” he said. “And I’ve loved bringing this man to life especially for a British audience, many of whom I think have never heard of him.”

Tony award winner Matthew Warchus (God of Carnage, Matilda) will be stepping into the artistic director spot next year.
