When Theatre503 was founded in 1982, it was an off-shoot of the Gate Theatre.
Its opening production (an adaptation of Fear and Loathing in Las Vegas) was so successful it transferred to the West End.
The theatre was re-launched in 2002 under its current name, making its 63-seat custom-built studio space (above The Latchmere Pub) into a home for new writing.
Since the re-launch, the theatre has premiered the work of writers such as Phil Porter, Phil Porter, Dennis Kelley, and Katori Hall (The Mountaintop, which transferred to Trafalgar Studios and eventually opened on Broadway).
To continue its commitment to writers, the theatre accepts unsolicited scripts (email only), produces extracts of works, and (in 2014) launched a Playwriting Award.
To encourage local residents to attend their productions, the theatre offers discount tickets and 2 for 1 offers for any attendee who lives in the SW11 postcode.
