About us

Showtime Challenge 48-Hour Musicals brings together a cast of 100 (or so) professional actors and talented amateurs, a 30-piece orchestra, and a hard-working production team. All volunteers, they pull together to produce a professional-standard all-singing, all-dancing musical in just 48 hours. Rehearsals start on Friday night. None of the cast have worked together on the show before this time. Then, 48 amazing, exciting, exhausting hours later, in a major West End theatre, it’s showtime!

See our PAST PRODUCTIONS page for full details, with photos, of our previous show!

Showtime Challenge is a not-for-profit organisation. All proceeds are either reinvested in operational costs of future productions or donated to charity.
