Question: Once a member of the Birmingham Repertory Theatre, what was Derek Jacobi's first action role? Passage:While in the sixth form, he starred in a production of Hamlet, which was taken to the Edinburgh Festival Fringe and very well regarded. At 18 he won a scholarship to the University of Cambridge, where he read history at St John's College and earned his degree. Younger members of the university at the time included Ian McKellen (who had a crush on him"a passion that was undeclared and unrequited", as McKellen relates it) and Trevor Nunn. During his studies at Cambridge, Jacobi played many parts including Hamlet, which was taken on a tour to Switzerland, where he met Richard Burton. As a result of his performance of Edward II at Cambridge, Jacobi was invited to become a member of the Birmingham Repertory Theatre immediately upon his graduation in 1960.
