After almost three decades on the air,Law & Orderis finally getting credit for an underrated element of its historic run. The long-running procedural was groundbreaking when it first premiered in 1990 because it combined police and legal drama — it was the first show to depict what happens after an arrest is made rather than ending each week’s episode with the cops closing their case. Additionally, both Law & Order andLaw & Order: SVUbase stories on real-life cases, something which was once novel but has now been adopted by many procedurals

Many of thebestLaw & Orderepisodesdepict the way crime and its aftermath affect victims, families, and defendants. For this reason, the procedural is more dependent on strong guest performances than most other crime dramas.Law & Orderhas done an especially good job of casting children and teenagers in intense roles. Notably, many of these young actors have grown up to become well-known in the industry as adults.

TheLaw & Orderfranchise’s best-kept secret is that booking a role on the iconic series is often the first step toward building a career as an actor. While some guest stars are already well-known when they participate in an episode, most are relatively obscure. Additionally,the franchise has a greater-than-average need for child actors, which allows performers of all ages to get their start. Many actors make a strong impression while appearing in only a small number of scenes, and some appear in multiple episodes as different characters.

Why The Law & Order Franchise Is The Perfect Starting Show In Hollywood

The Procedural Requires Lots of One-Off Roles

Itsprocedural formula requires each episode to utilizeLaw & Order’sguest actorsfor both major and minor parts. During the first half of each episode, the detectives interview a lot of people, some of whom only appear in one or two scenes. For example, the series may need guest actors to play hot dog vendors, parents picking up their kids from school, taxi drivers, or other witnesses who only appear briefly, and there is also usually an arraignment judge.Some actors shine so brightly in these small roles that the franchise invites them to play other small partsoccasionally.

Ed Wheeler Was So Good, Law & Order Had Him Play Six Different Characters

The late character actor Ed Wheeler was so good at what he did that Law & Order featured him as six separate minor characters over the years.

Of course, there are also bigger roles available within each episode — andsome of these are among the most intense or dramatic parts available on network television.The actors playing victims, witnesses, defendants, and lawyers have the opportunity to explore unique and emotional roles. Thus, appearing inLaw & Orderallows them to stretch their acting muscles and add clips to their portfolio that demonstrate a wide range of abilities.

Since the franchise is filmed on location in New York, actors who live there can build their career without having to travel. Specifically, the franchise often employs out-of-work Broadway stars, allowing them to make the transition from stage work to television roles. This also helps support Broadway actors' careers when they are between shows, and many such actors picked up work in the franchise when Broadway was closed during the 2020 COVID lockdown.

Over The Course of Decades, Many Actors Have Gone Onto Bigger Things

Since most actors are not well-known when they first guest star onLaw & Order,they aren’t recognizable until rewatching old episodes. For example,Sabrina Carpenter made her acting debut onLaw & Order: SVUat age 11, but she played only a small role and was not known then. Thus, it can be surprising to rewatch an episode and recognize someone who wasn’t an important part of theLaw & Ordercast at the time.
