Brief:

• A brand new restoration of The New Avengers which was simultaneously issued on 4K (UHD, deluxe packaging, black-coloured outer box) Blu-ray (HD, deluxe packaging, orange-coloured outer box) and DVD (SD, cream and cerise sleeve in plastic case) by StudioCanal in the United Kingdom.
• Two printed booklets were also included: a 64-page Collector's Edition Booklet, comprising essays by Samuel Clemens, Dick Fiddy, David Richardson, Andrew Roberts and Kim Newman, and a Collector's Edition Comic, comprising reproductions of comic strips featured in the 1977 and 1978 New Avengers annuals (originally issued by Brown Watson). The main booklet included a tribute to author and Avengers fan Dave Rogers, who had sadly died on 5th July 2025.
• Package design was by Sam Smyth.
• The disc was designed with multiple territories in mind, starting up with a menu choice offering 'Deutschland', 'France' and 'United Kingdom'. The French and German menus offer dubbed audio in these languages or English with locked subtitles. Interestingly, the actual French discs have a different opening menu choice and subtitles are not locked.

• A well-attended launch event was held at Riverside Studios in Londonon the afternoon of Sunday 9th November 2025. The new restoration of The Eagle's Nest was screened in full. The intention had been to follow this with the new documentary, The Impact of The New Avengers: Reinvented for a New Era, but this was not available to screen on the day. Consequently the featurette Restoring The New Avengers and a lengthy excerpt of Kicks, Flips & Spy Tricks: The Stunt Magic of The New Avengers were shown instead. The event also had a Q&A session with guests Cyd Child, Samuel Clemens, George Clemens, Rodney Marshall (Avengers author and son of writer Roger Marshall) and Dick Fiddy.

• Due to format capabilities - or indeed their lack - these 4K discs did not include the option to additionally view audio commentaries with picture-in-picture video, which was available on some episodes on the equivalent Blu-rays.

• There were minor issues with this release: The Last of the Cybernauts...?? opens with out of phase sound but this corrects itself after about 5 seconds, and The Gladiators is missing approximately 1 second of footage during the fight sequence immediately after the opening titles. This was previously edited for DVD to remove an ear clap which was then only certifiable at a '15' BBFC rating in the United Kingdom. By 2025, it would only have warranted a '12', which was the overall rating of this box set.

• Additionally, StudioCanal made the controversial decision to adjust the audio pitch to match the original transmissions which unavoidably exhibited "PAL speed up". This was an unfortunate consequence of the PAL broadcast system, which ran at 50Hz and therefore dictated a frame rate of 25 frames/50 fields per second. With the episodes shot at 24 frames per second this necessitated a speed up to 25 fps for transmission. Generally, the original camera frame rate is considered authentic, but here StudioCanal presented video at 24fps with audio mimicking 25fps.
