After completing a nine-month acting course in Turkey, Mehmet decided to become a director. He put an ad in
The Stage inviting applicants to join a new theater company, and began putting on plays in pub theaters. Soon after, Ergen co-founded the
Southwark Playhouse with Juliet Alderdice, Tom Wilson and Annabelle Harvey-Longmire in 1993. Ergen and his colleagues created the Theater after identifying possible areas in need for an accessible theater, which would provide its surrounding community with a hub for creativity. They converted a disused workshop into a theater space which quickly gained popularity, and by working closely with local teachers, the city council, businesses and government agencies, they were able to develop an innovative, free at source, education program. He was also the theatre's first artistic director between 1993 and 1999. Mehmet went on to become
Associate Producer at the BAC (
Battersea Arts Centre) from 1999 to 2001. While there he directed
Scott Joplin's
Treemonisha,
Kurt Weill's
Lost in the Stars and had a workshop performance of
Marc Blitzstein's
The Cradle Will Rock. It was during this period he also founded The
Grimeborn opera festival. The artistic director at the time, Tom Morris, asked Ergen to create something new and different from the normal operatic preconceptions in a manner similar to that of Tete-a-Tete of the Riverside Studios.
Grimeborn was his creation, an opera and musical theater
festival that now runs yearly at
Arcola Theatre. In 2000, Ergen founded Arcola Theatre in the
London Borough of Hackney with Leyla Nazli. They converted an old shirt factory while teaching in
Dalston, East London, into a fringe venue. Ergen acquired £5,000 of start-up money and sent invitations to all the actors and directors he knew to join him in a paint party. They even recycled cutting tables into benches for the audience. Ergen's role in the development of London theater has often been noted in the media. Arcola is known for its bold selection of plays; "a melting pot of classic revivals and new work … aspiring theater professionals make a beeline for it prepared to work there for less than a pittance; respectable touring outfits, such as the
Oxford Stage Company and
Out of Joint, have been queuing up to use its cavernous main space and acquire a bit of its urban cred". Past productions have included
Peter Weiss's
Marat/Sade and
David Farr's version of
Crime and Punishment. There were an estimated 30,000 visits in 2003. == Work in Turkey==
