Hollywood Powerhouse Buys ATG and Why It Matters for UK Theatre

Douglas McFarlaneAugust 12, 2026

A New Chapter for a Familiar Name

For more than two decades, we’ve had the privilege of reviewing productions at ATG theatres across the UK. From London’s West End to regional venues including the Bristol Hippodrome, Edinburgh Playhouse, Manchester Opera House and the Liverpool Empire, ATG has been responsible for bringing some of the world’s biggest musicals, plays and live entertainment to audiences nationwide.

This week, one of the biggest stories in live entertainment broke when ATG Entertainment agreed to be acquired by Mari, the global live experiences company founded by Hollywood super-agent Ari Emanuel. The deal, reported to be worth around £4.5 billion, brings one of Britain’s most influential theatre companies under the ownership of one of the entertainment industry’s most recognisable figures.

Who Is Ari Emanuel?

Although Ari Emanuel may not be a household name in the UK, his influence is enormous. He built one of Hollywood’s biggest talent agencies, representing leading actors, directors, writers, athletes and entertainers while helping shape some of the world’s most successful entertainment businesses. His new company, Mari, was created to focus entirely on live experiences and has already invested heavily in sport, festivals and premium entertainment. Acquiring ATG is another major step in that strategy.

Why This Acquisition Matters

This acquisition is significant because ATG is far more than a theatre owner. The company operates around 70 venues across the UK, Europe and North America while also producing and investing in many of the world’s biggest stage productions. Millions of people attend performances in ATG theatres every year and its influence extends across both the West End and Broadway.

For those of us who regularly attend the theatre, this is more than another corporate takeover. It is a clear indication that live theatre remains a valuable and growing part of the entertainment industry. At a time when streaming services and digital content dominate so much of our leisure time, a multi-billion-pound investment in theatre demonstrates real confidence in the future of live performance.

What Could Change?

Audiences are unlikely to notice any immediate changes. Productions already on sale will continue as planned and theatres will operate as they always have. The more interesting question is what happens over the coming years.

Mari brings experience from across the global entertainment industry and has strong relationships with major artists, producers and promoters. That could create opportunities for greater collaboration between Broadway and the West End, increased investment in theatre technology, enhanced visitor experiences and continued improvements to many of the historic venues within ATG’s portfolio.

Good News for Regional Theatres

For regional theatres, this could also be encouraging news. ATG has long played an important role in bringing major touring productions beyond London, allowing audiences across the UK to enjoy world-class theatre without travelling to the capital. Continued investment in these venues benefits not only theatre lovers but also local economies, hospitality businesses and the wider creative industries.

A Strong Vote of Confidence

The timing is particularly interesting. Theatre has recovered strongly since the pandemic, with many productions once again enjoying excellent ticket sales and attracting new audiences. Investors increasingly recognise that live experiences offer something that cannot be replicated on a screen. The shared excitement of a packed auditorium, the energy of a live performance and the emotional connection between performers and audience remain as compelling as ever.

Our View

Having reviewed productions at ATG theatres for more than twenty years, we’ve seen first-hand the quality and variety of entertainment the company has brought to audiences across the country. We hope this new chapter continues that tradition while providing fresh investment and new opportunities for theatres, performers and audiences alike.

If Mari delivers on its ambitions, this acquisition could prove to be one of the most important moments for the UK theatre industry in many years. For theatre lovers, that can only be good news.
