The Ultimate Unreliable Narrator: An Actor's Schedule
In the pristine, clockwork world of a whodunnit, every detail is supposed to matter. The misplaced letter, the side-eye glance, the alibi that’s just a little too perfect—these are the breadcrumbs that lead us to a satisfying conclusion. Yet, behind the scenes,
a far more chaotic force is at play: actor availability. A-list guest stars, who can give a show like Only Murders in the Building or Poker Face a surge of prestige and viewership, are often juggling multiple projects. Their availability might be limited to a few specific weeks, or even just a handful of days scattered across a production schedule. For a genre that relies on meticulous planning, this is the ultimate wrench in the works. A writers' room might have a perfectly crafted outline, but if the actor slated to be the surprise villain has to leave two weeks early to shoot a blockbuster film, the entire plot must be re-engineered.
The 'Bookend' Victim or Killer
One of the most common ways writers adapt is by using what’s known as “bookending.” If a big-name actor has only a few days to spare, they're often cast in roles that can be filmed compactly. This makes them perfect candidates for being the initial victim—a character who appears prominently in the first act and then exists only in flashbacks—or the killer who is revealed in the final act. Think about it: the victim’s scenes can often be shot all at once, even out of sequence. Likewise, a killer might be a background presence for most of the season, requiring minimal screen time until their big confession scene, which can be filmed during their short window of availability. Shows known for their star-studded guest lists often master this technique. The structure allows them to feature exciting talent without being beholden to their complicated schedules for the entire production block.
From Prime Suspect to Red Herring
A character's entire narrative arc can be determined by scheduling. A role initially conceived as a major red herring—someone who seems guilty for several episodes before being cleared—requires an actor to be consistently available. If that actor suddenly becomes unavailable for a crucial stretch of filming, the writers have a choice: recast the role or pivot the story. More often than not, they pivot. That character might be abruptly “sent out of town” on a contrived business trip, or their suspicious behavior might be explained away far earlier than planned. Conversely, a minor character played by an actor with unexpectedly open availability might suddenly find their role expanded. They can be woven into more scenes, given new subplots, and potentially even be elevated to become a prime suspect or the killer, simply because they were physically present on set.
The Mad Scramble in the Writers' Room
The process is less about pristine blueprints and more about organized chaos. Showrunners like Rian Johnson have noted that for a series like Poker Face, casting can happen week-to-week during shooting. This creates a dynamic where writers are constantly adapting. In some writers' rooms, characters are tracked on a large board with colored index cards, making it easier to visualize who is available for which scenes and how their absence might affect the main plot. This logistical puzzle forces a unique kind of creativity. A plot hole created by a scheduling conflict must be plugged with a new twist. An actor’s unexpected departure might lead to a more interesting, unforeseen culprit. This reactive style of writing means that the mystery you see on screen is often the product of intense, last-minute problem-solving, turning a logistical nightmare into narrative gold.
