The Cotswold Players first half century was celebrated with a special exhibition designed and directed by Howard Mann and a Golden Jubilee production of 'Under Milk Wood' by Dylan Thomas was directed by Elizabeth Jupp.

In 1971 the Chairman, Charles Hunt, resigned because the committee agreed to stage a production of Brendan Behan’s “The Hostage”, a play that Hunt thought was beyond the pale.

In 1972 to celebrate Cotswold Players’ Diamond Jubilee, a poll was taken among the patrons to see which play they would like to see and 'Under Milk Wood' was chosen again by 70 per cent of those voting. This time it was directed by Michael Bishop with a cast of sixty eight, a dog and a cat!

Throughout the 1980s and 90s the Players continued to attract good audiences and win awards in various competitions including the GDA One Act and Full Length Play Competitions, the Bristol Evening Post Rosebowl, Stroud One Act Play Festival, HTV West Festival, Malmesbury One Act Play Festival and the Gloucester One Act Play Festival.

In 2001 the members installed an orchestra pit.  But the Playhouse was badly in need of some care and attention.  The seats were in poor condition, the decor decidedly tatty, the heating noisy and the balcony was getting so rickety that there was a danger that the Stroud District Council would not issue a theatre licence.  So in 2002, the auditorium was entirely rebuilt with brand new, fully raked seating and the bar and lounge completely remodelled.   New lighting and sound rooms were installed and a lighting workshop built above.

In 2006, the stunning production of Peter Pan won the NODA Award for Excellence, the Rose Bowl Award for Best Musical, the GDA Best Musical, Best Set Design and Best Costume.

In 2007/08 a major development was undertaken when the old lounge was demolished and a major extension built around two sides of the building.  This included a dance studio which doubles as a rehearsal room, an office, stage workshop and store, costume store and new toilets including one for the disabled.   The original cost estimate was £284k but the final bill was around £500k.
