We are excited to announce that CO2 will be producing Charlie & The Chocolate Factory in Autumn 2025 and COS will be producing Guys & Dolls in Jan/Feb 2026 at the Mercury Theatre, Colchester.

We are proud of the award/winning standards our productions achieve, and the opportunity this provides for aspiring creative partners. Would you like to get involved as a creative in either of these or any future COS/CO2 productions?

We are currently on the lookout for musical directors, directors and/or choreographers/assistant directors. If you (or someone you know) would be interested in providing the creative expertise behind our high quality productions and would like more details then please contact us with your expression of interest and a CV of any similar work you have done before if applicable, on secretary@colchesteroperaticsociety.co.uk.

More information about casting and getting involved backstage for these productions will be published on our website and social media platforms in due course.

We are pleased to announce that, following our auditions, we have cast our production of The Little Mermaid.

We saw 76 auditionees during our first round of casting and with such a high standard of singing, dancing and acting our panel had the unenviable and difficult task of casting only 45 (including our dual cast role of Flounder). We then held additional auditions for the role of Ariel, receiving 39 applicants. From this we found our Ariel making our cast list complete.

Whether cast or not we think everyone who auditioned should be proud of themselves!

We thank all of our audition panel, our readers, members of our committee and all who auditioned for their time and for helping all three audition days run swimmingly. We can’t wait to start rehearsals in September.

Don’t forget to get your tickets and that there is a 15% discount when you book both Legally Blonde and The Little Mermaid together

The registration to be in the cast for The Little Mermaid at the Mercury Theatre 31^st Jan – 9^th Feb 2025. is now open!

Please visit our Casting Call page for more information.

We are absolutely delighted to announce our cast of 44 members for our centenary concert: “Some Enchanted Evening: celebrating 100 years of Colchester Operatic Society” 

Join this talented cast on Friday 21st June 2024 at the Mercury Theatre for a special one night only centenary celebration concert packed with songs from a vast back-catalogue of shows we have performed locally over the last 100 years.  

The cast will be musically directed by the talented Neil Somerville and be joined by special guests from our youth group, “CO2”, and also past members from the Society’s history; some of whom have become stars of stage and screen in their own right.

Let them take you on a musical journey linked with tales of the Society’s history, as they fill the Mercury Theatre auditorium with the sound of music and beautiful harmonies.
