1. Meghan Treadway Trained at Royal Central

Treadway trained at the Royal Central School of Speech and Drama.

That became her professional base.

Drama training led quickly into physical theatre, puppetry and performance work. Her career then moved between stage acting, television, film and theatre education.

It is a mixed career.

She does not stick to one format. Theatre remains a big part of her work even as her television profile has grown.

2. Her First Professional Job Was Unusual

Her first job after drama school sounds quite different from a standard acting debut.

Complicité says Treadway worked on A Dog’s Heart, where she was puppeteering cats in the background of a dog’s dream.

Pretty unusual start.

The production was created with Complicité and English National Opera. Complicité records her involvement in the project in 2010.

That early job also makes sense when looking at what came later. Treadway kept working with physical theatre, puppetry and ensemble-led productions.

3. Complicité Became a Major Career Connection

Treadway has built a long working relationship with Complicité.

She has performed in the company’s productions of A Dog’s Heart and The Magic Flute. She was also part of Complicité Does A Level Drama.

But acting is only one part.

Complicité says she has worked as a director or assistant director on projects such as A Complicité Journey, Barking Nuns and Carnival Journeys. She has also worked as a teacher and workshop facilitator.

The company’s 2024 A Complicité Journey page identifies her as a Complicité Associate.

That helps explain her career clearly. She acts, but she also works behind the performance process.

4. Her Theatre Credits Cover Major Productions

Treadway’s stage CV is long.

One recognised credit is War Horse with the National Theatre and New London Theatre. Her professional theatre record also includes Venus in Fur, The Collector, Treasure Island, Hansel and Gretel, Alice’s Adventures Underground and The Magic Flute.

She later joined Witness for the Prosecution at London County Hall.

Her role was Romaine Vole.

That production added another major London theatre credit to a career already built around very different kinds of live performance.

She has moved between opera-based work, physical theatre, traditional plays and large commercial productions. That range shows up repeatedly in her professional CV.

5. Flack Became an Important Television Credit

Television became a bigger part of Treadway’s work as her career developed.

She appeared across series one and two of Flack. Her agency lists both seasons among her main television credits.

The show starred Anna Paquin and followed the chaotic world of a London public-relations agency.

Treadway played Belle.

This was more substantial than a single guest appearance and remains one of the recurring television credits associated with her screen career.

6. Her TV Work Expanded Across Major Shows

More screen roles followed.

Treadway’s verified television credits include:

Endeavour
Ten Percent
Dreaming Whilst Black
The Outlaws
The Crown
One Day
Trying

These credits are listed across her current AHA Talent profile and Complicité profile.

Basically, viewers may recognise her without immediately knowing her name.

Netflix viewers may have seen her in One Day or The Crown. Apple viewers may know her from Trying. BBC audiences may recognise her from The Outlaws or Dreaming Whilst Black.

Her film credits include Antoine Fuqua’s Infinite and Carlos Marques-Marcet’s Anchor and Hope.

7. Murder Before Evensong Raised Her Screen Profile

A major recent role came with Murder Before Evensong.

Treadway was cast as Honor De Floures.

AMC Networks and Channel 5 announced her alongside Matthew Lewis, Amanda Redman, Amit Shah, Adam James, Marion Bailey and other members of the six-part mystery drama.

The series comes from Reverend Richard Coles’s Canon Clement stories.

Matthew Lewis plays Canon Daniel Clement. The story follows a quiet English parish that becomes caught up in murder, secrets and a police investigation.

Treadway’s agency lists Murder Before Evensong as a series regular credit.

The show premiered on Acorn TV in the US and Canada on 29 September 2025, with Treadway included among its main announced cast.

For readers searching Meghan Treadway after seeing her on television, this is one of the key roles to know.

8. Meghan Treadway Is Back on Stage in 2026

Her theatre work continues.

As of September 2026, Treadway plays Abigail in Alex Rugman’s The Urmetazoan at Hampstead Theatre.

Anna Ledwich directs the production.

The cast also includes Dorothea Myer-Bennett as Alice and Ben Allen as Will. Hampstead Theatre lists the production from 18 September to 24 October 2026.

It is a small cast.

That puts Treadway directly at the centre of the production rather than inside a large ensemble.

Her return to Hampstead-stage work also shows something consistent about her career: television success has not pulled her away from theatre.

9. Another TV Role Is Already Listed

There is more screen work ahead.

Treadway’s current AHA Talent profile credits her as Emma Dawkins in series four of The Marlow Murder Club. The agency lists Steve Barron as director.

UKTV confirmed the fourth series in June 2026.

The new run contains six episodes and is scheduled for 2027 on U and U&DRAMA in the UK. MASTERPIECE is the US broadcaster.

The core returning cast includes Samantha Bond, Cara Horgan, Jo Martin and Natalie Dew.

So Treadway’s television work looks set to continue alongside her stage career.

Meghan Treadway’s Work Beyond Acting

Acting gets most attention.

Still, her work with young performers and theatre education matters too.

Complicité says Treadway has worked as a teacher and facilitator across many workshops. She has also helped direct outreach projects in schools and communities around the UK.

Her work has gone overseas as well.

The company records her attendance at an international teaching-artists conference in Taiwan.

This side of her career gives a clearer picture of what she actually does day to day. She moves between performing, teaching, directing support and creative projects.
