Prime Video’s Hit 2-Part Thriller Officially Adds ‘Mad Men’ and ‘True Detective’ Stars



[

Prime Video’s hit YA thriller series We Were Liars is coming back for a second season, and it looks like the new season will be exploring the mysterious past of the Sinclair family. The series has just announced the casting of a number of new actors for the upcoming second season, which has not yet set a release date.

Season 2 will flash back to the early days of the Sinclair family, with many of the new additions playing younger versions of the show’s characters. Patriarch Harris Sinclair, played in the present by David Morse, will be portrayed in his youth by Josh Dallas (Once Upon a Time), while his wife Tipper, played by Wendy Crewson in the present, will be played by Peyton List (Mad Men). (This Peyton List is not to be confused with the other actress of that name, who starred on Cobra Kai and School Spirits.) Eldest Sinclair sister Carrie, played by Mamie Gummer in the present, will be played by Parker Lapaine (House of the Dragon); middle sister Penny, normally played by Caitlin FitzGerald, will have her younger incarnation played by Elysia Roorbach (The Pitt); and youngest sister Bess, played in the present by Candice King, will be portrayed by Madison Wolfe (The Hunting Wives). Also joining the cast is Costa D’Angelo (Thrash) as Pfeff, a mysterious college kid who upends the lives of the Sinclair sisters.



















































Collider Exclusive · TV Medicine Quiz
Which Fictional Hospital Would You Work Best In?
The Pitt · ER · Grey’s Anatomy · House · Scrubs

Five hospitals. Five completely different ways medicine goes sideways on television — brutal, chaotic, romantic, brilliant, and ridiculous. Only one of them is the ward your instincts were built for. Eight questions will figure out exactly where you belong.

01

A critical patient comes through the door. What’s your first instinct?
Medicine under pressure reveals who you actually are.





02

Why did you go into medicine in the first place?
The honest answer says more about you than the one you’d give in an interview.





03

What do you actually want from the people you work with?
Who you want beside you under pressure is who you are.





04

You lose a patient you fought hard to save. How do you carry it?
Every doctor who’s worked a long shift has had to answer this question.





05

How would your colleagues describe the way you work?
Your reputation on the floor is usually more accurate than your self-image.





06

How do you feel about hospital protocol and procedure?
Every institution has rules. What you do with them is a choice.





07

What does this job cost you personally?
Nobody works in medicine without paying a price. What’s yours?





08

At the end of a long shift, what keeps you coming back?
The answer to this question is the most honest thing about you.





Your Assignment Has Been Made
You Belong In…

Your answers have pointed to one fictional hospital above all others. This is the ward your instincts, your temperament, and your particular brand of dysfunction were built for.


Pittsburgh Trauma Medical Center

The Pitt

You are built for the most unsparing version of emergency medicine television has ever shown — one that puts you inside a single fifteen-hour shift and doesn’t let you look away.

  • You need your work to be real, not romanticised — meaning over drama, honesty over aesthetics.
  • You find purpose inside the work itself, not in the chaos surrounding it.
  • You’ve made peace with the fact that this job takes from you constantly, and gives back in ways that are harder to name.
  • Pittsburgh Trauma Medical Center demands exactly that kind of person — and you would not want to be anywhere else.


County General Hospital, Chicago

ER

You are the person who keeps the whole floor running — not the most brilliant in the room, but possibly the most essential.

  • You show up, do the work, absorb the losses, and come back the next day without needing the job to be anything other than what it is.
  • You care about patients as individual human beings, not as cases to solve or dramas to live through.
  • You believe in the system even when it fails you — and you understand that emergency medicine is about holding the line just long enough.
  • ER is television about endurance. You have it.


Grey Sloan Memorial Hospital, Seattle

Grey’s Anatomy

You came to medicine with your whole self — your ambition, your emotions, your relationships, your history — and you have never quite managed to leave any of it at the door.

  • You feel things fully and form deep attachments to the people you work with.
  • Your personal and professional lives are permanently, chaotically entangled — and that entanglement drives both your greatest disasters and your most remarkable saves.
  • You understand that extraordinary medicine often happens at the intersection of clinical skill and profound human connection.
  • It’s messy at Grey Sloan. You would not have it any other way.


Princeton-Plainsboro Teaching Hospital, NJ

House

You are drawn to the problem above everything else — the symptom that doesn’t fit, the diagnosis hiding underneath the obvious one.

  • You’re not primarily motivated by the patient as a person — though you are capable of caring, even if you’d deny it.
  • You work best when the stakes are highest and the standard answer is wrong.
  • Princeton-Plainsboro exists to house one extraordinary, impossible mind — and everyone around that mind is there because they’re smart enough to keep up.
  • The only way forward here is to think harder than everyone else in the room. That is exactly what you do.


Sacred Heart Hospital, California

Scrubs

You understand that medicine is tragic and absurd in almost equal measure — and that the only sane response is to hold both of those things at the same time.

  • You are warm, self-aware, and funnier than most people in your field.
  • You use humour to get through terrible moments — and at Sacred Heart, that’s not a flaw, it’s a survival strategy.
  • You lean on the people around you and let them lean back. The laughter and the grief are genuinely inseparable here.
  • Scrubs is a show about learning to become someone worthy of the job. You are still very much in the middle of that process — which is exactly right.

What Is ‘We Were Liars’ About?

We Were Liars follows the travails of the wealthy Sinclair family, who own their own private island, Beechwood. Cady Eastman (Emily Alyn Lind) is the eldest grandchild; she is close friends with her cousins, Mirren (Esther McGregor) and Johnny (Joseph Zada), and their friend Gat (Shubham Maheshwari), who collectively call themselves the Liars. The rest of the family is riven by disputes and squabbles, driven by the desire to inherit the family mansion, Clairmont, from dementia-stricken patriarch Harris. The series follows two timelines; one, as Cady and her friends arrive at Beechwood for the summer, and another two years later, as Cady suffers from amnesia, unable to remember what accident befell her. The truth may be too terrible for her to remember…

We Were Liars is an adaptation of the 2014 novel of the same name by E. Lockhart. It is written, executive produced, and showrun by Julie Plec (The Vampire Diaries) and Carina Adly MacKenzie (Roswell, New Mexico). Also executive producing are Emily Cummins (The Endgame) for My So-Called Company, Brett Matthews (Legacies), Marguerite MacIntyre (Vampire Academy) and author Lockhart.

We Were Liars will be returning for a second season; no release date has yet been announced. Stay tuned to Collider for future updates.
