Stubbs surprises drama students

British actress Imogen Stubbs thrilled pupils at a college in London this week (begs05Dec11) by joining a drama class and performing scenes written by the students.

The Jack & Sarah star surprised a group at Lambeth College in the U.K. capital and shared her acting advice with the youngsters, who are part of the prestigious Donmar Warehouse's play-writing project for teenagers.

Stubbs tells Britain's Evening Standard, "Their plays weren't just deep but cool too, and very original. It was very brave of them.

"If they were nurtured, they could go far. I hope they do go on and write."
