Casting is the make-or-break of a movie or television program. You’ve got your script so keen it nearly sings, and your director’s a genius when it comes to seeing things, but if the actors are not inhabiting their characters, the magic never occurs. When the casting directors do get it right, however? That is when the planets form a lineup, and a character or group of characters becomes indelible. There are performances so accurate that it’s hard to picture anyone else in those shoes. With that said, let’s number down 10 of the best cast choices and castings in film and television history, the type of decisions that made good projects into all-time icons.

10. The Cast of The Golden Girls: Four women, one unbeatable sitcom formula
For one to be able to point at the pinnacle of sitcom perfection, it would hardly be possible other than leading to The Golden Girls. Bea Arthur, Rue McClanahan, Betty White, and Estelle Getty were more than just funny; they were magic in a jar. Not only did they all have something uniquely different to offer, but they also managed to create a bond so natural that it still seems like they did not have to put in a lot of effort almost 30 years after their last collaboration. Their banter, their movement, and even their emotional instincts with laughter were at the very center of a whole new era of TV shows. The four ladies even acted beyond being roommates; they became family for people from different parts of the world, therefore, turning the concept of a true ensemble, which is timeless, into reality.

9. Sanford and Son Cast: A comedy roster with no weak links
Most TV shows rely heavily on a leading actor to carry the whole act, but talent surrounded the Sanford and Son from the ceiling to the floor. Redd Foxx’s sharp, sneaky, and sarcastic sense of humor fit perfectly with Lawanda Page’s brash, witty delivery, and every one of the supporting actors provided their bit of seasoning to the mixture. The cast in its entirety made a sitcom that is still regarded as one of the best comedies in the history of television. The whole thing was not only about gags as well it also the rhythm, the timing, and the chemistry that turned every performance into a masterpiece. The thing with an ensemble at its most efficient is that you can remove any actor from the group and put them in the limelight, where they will still shine.

8. Married with Children Cast: Dysfunction at its most comedic
While The Golden Girls treated us to all manner of good vibes and a heart of gold, Married with Children, conversely, provided us with the very opposite, and we couldn’t get enough of it. The Bundys were crude, boisterous, and unapologetically disorganized, but the actors performed it so believably that it became comedy gold. Ed O’Neill, Katey Sagal, Christina Applegate, and David Faustino were blessed with the highest quality of chemistry that was abrasive yet impossible to resist. Their off-screen amiable relationships transformed into a very distorted form of on-screen reality, which itself rendered the dysfunction almost…real. Therefore, they modeled the TV family model very well again, not just any way, but with a facetious mix of sarcasm and silent jokes.

7. Frasier Cast: Witty lines honed to a blade
It is laugh-giving that Frasier never centered around Grammer alone. Regardless, Fras was intelligent; yet his genius was only because the characters he was residing alongside were present. Niles, Martin, Daphne, and Roz were not the co-conspirators, but the full characters that filled out all of the scenes. Their conversation was witty, as they traversed that fine line between sophisticated comedy and street-level humor. Recurring and guest stars were to the show what icing on a cake is to the cake; they were providing a depth and richness to the world that felt lived-in and side-splitting. A spinoff rarely reaches or tops the success of its mother show, but thanks to the savvy casting, Frasier has worked its way to becoming one of the all-time greats on its own.

6. Seinfeld Cast: Weirdos who became TV legends
Jerry, Elaine, George, and Kramer appeared to be a mess in the brainstorming session, but an amalgamation of four neurotic and egotistical eccentrics. And the TV’s characters became the pulse of one of television’s most cherished shows in the entire history of television. Jerry Seinfeld, Julia Louis-Dreyfus, Jason Alexander, and Michael Richards came together like a crazed band but remarkably happened to be in complete synchronization with each other. Their varying personality traits, mannerisms, and a few antagonist characters offered comedic skills without end. Now imagine it with a cast of memorable recurring characters; that’s my definition of magic in the bottle: not only does it amuse those gathered around, it rewrites the sitcom storytelling since.

5. Alan Rickman as Severus Snape: The ideal representation of complexity
No casting choice has ever had the same quality of feel-good inevitability as Alan Rickman taking on the robes of Severus Snape. From the very first cold line delivery, he was just the character. Rickman’s portrayal of Snape’s frosty demeanor, along with a hint of the vulnerability latent beneath, lent depth that became richer as the series progressed. Even J.K. Rowling has stated she couldn’t envision anyone else in the role. His portrayal turned an ethically gray character into one of the most engaging and memorable characters throughout the entire Harry Potter series.

4. Robert Downey Jr. as Tony Stark: The soul and heart of the MCU
Robert Downey Jr. had to be that one Iron Man when Marvel chose to hire him to play the character of Tony Stark, a risk that became the riskiest in the history of the superhero film franchise. The wit, charm, and willingness of the ego that came together with the vulnerability of Downey led to the very essence of Iron Man. Instead of merely being one of the characters, he became the hub of the MCU. With every smirk, one-liner, and endearing moment, RDJ embodied a hero who was raw, imperfect, and deeply human. Without him, it is difficult to imagine the Marvel behemoth ever reaching that pinnacle.

3. James Earl Jones as Darth Vader: A voice that embodied evil
Darth Vader is a commanding presence in and of himself, but even so, it is James Earl Jones’s voice that he is unable to forget. Not only did this deep, commanding voice convey menace, but it also bestowed nobility upon the character. Jones brought Vader out of the ocean of masked thugs to become an icon of one of the most recognizable film icons of fear and authority. Without the legendary voice, it is difficult to imagine that Vader could have the same artistic and cultural influence. What his singing career informs us is that sometimes the best casting efforts aren’t character-based but are voice-based, whereby voices that still echo in generations are picked for the role.

2. Heath Ledger as The Joker: Madness immortalized
To begin with, the fans were not convinced Heath Ledger was suitable to portray the Joker. And then, with his performance in The Dark Knight, he shut the doubts up altogether. He took madness, unpredictability, and dark humor to his portrayal and gave the character a whole new definition that was as brilliant as it was disturbing. From the smeared makeup to the unnerving tics, his performance was revolutionary. He wasn’t playing the role of the Joker-he was chaos personified. Additionally, his performance ended up establishing a new standard on top of comic book villains in the genre’s lore, with an extended influence on how film villains have since been built.

1. Javier Bardem as Anton Chigurh: Fear, perfected
No Country for Old Men’s Javier Bardem’s Anton Chigurh could have been a malevolent embodiment, defining what evil may be in one character in terms of both imagery and sound. With his droning tone, unsettling silence, and that memorable coin-flip scene, Bardem emerged as one of the most frightening movie villains in history. It is still what makes it so terrifying how it all works so slickly; he isn’t like the people who have to scream and resort to grand gestures to scare. The mere fact that he is sufficient to get the chills down your spine. It is nearly a form of miracle that the actor and the role are so inextricably linked that the casting choice is as fantastic as this one.

Not only are these performances and castings merely a sampling of great casting, they are the standard by which others are measured. Their purpose is to emphasize that the union of an actor’s abilities and a character is not merely a total of the parts. In the instance of a cast of a classic sitcom or even a single performance that revives a series, perfect casting can turn legends into legends.
