Several of the greatest Batman: The Animated Series episodes ever featured a multitude of major stars. Few animated shows have ever matched the legacy of DC’s Batman: The Animated Series. Long before celebrity voice casting became the norm in animation, Batman: TAS was quietly bringing in major talent from film, television, and music.
These are not just for blink-and-you-miss-it cameos either; these actors delivered fully realized performances that elevated the material and added unexpected depth to Gotham’s world. Celebrated for its noir-inspired storytelling, mature themes, and unforgettable performances, Batman: TAS redefined superhero animation and set a standard that still influences the genre today.
Beyond its iconic take on Batman and his rogues’ gallery, the show had another secret weapon: an impressively stacked roster of guest stars. What’s even more impressive is how often episodes featured multiple recognizable voices at once, creating a kind of hidden all-star lineup that many viewers didn’t fully appreciate at the time.
Looking back, it’s clear that some episodes doubled as showcases for serious acting talent. Indeed, these six standout episodes prove just how stacked the series really was.
Batman: TAS Season 2, Episode 17 “The Lion And The Unicorn”
“The Lion and the Unicorn” is one of those episodes that feels distinctly different from the typical Gotham-set story – and part of that uniqueness comes from its casting. The Batman: TAS episode sends Alfred Pennyworth into the spotlight, uncovering his past as a British intelligence agent, while also introducing a pair of memorable villains brought to life by surprising talent.
Iconic musician Adam Ant voices the henchman Bert, one half of the duo sent by Red Claw to abduct Alfred. It’s a fun bit of casting that adds a layer of personality to what could have been a fairly standard villain role. Alongside him is Red Claw herself, voiced by Kate Mulgrew, delivering a commanding performance before her iconic turn in Star Trek: Voyager.

The pairing of these two performers helps elevate the episode’s espionage tone, making it feel more like a spy thriller than a traditional superhero story. Combined with Alfred’s rare time in the spotlight, it’s a standout example of how Batman: TAS used casting to enhance even its more unconventional episodes.
Batman: TAS Season 2, Episode 5 “House And Garden”
“House and Garden” leans into psychological horror, but it also quietly features a pair of recognizable voices that add texture to its eerie narrative. The episode centers on Poison Ivy attempting to build a “perfect” domestic life, blending unsettling themes with Batman: TAS’s signature gothic tone.
Will & Grace star and comedy legend Megan Mullally appears as Cindy, a Gotham University student dating Dick Grayson. While it’s a smaller role, Mullally brings a grounded charm that contrasts nicely with the episode’s increasingly strange developments. At the same time, veteran voice actor Jim Cummings takes on the role of Saunders, a wealthy Gothamite who becomes one of Ivy’s victims.
Cummings is no stranger to animation, famously voicing Winnie-the-Pooh, but pairing him with a rising live-action talent like Mullally gives the episode a subtle star power boost. It’s another example of how Batman: TAS blended experienced voice actors with recognizable names, creating a cast that felt both dynamic and unexpectedly prestigious.
Batman: TAS Season 2, Episode 13 “Showdown”
“Showdown” stands out as one of the most atmospheric episodes in Batman: TAS, taking viewers into a Western-inspired setting that expands the world beyond Gotham. But it’s not just the setting that makes the episode memorable – it’s the incredible lineup of voice talent. The acclaimed movie star Malcolm McDowell voices Arkady Duvall, bringing a charismatic yet dangerous edge to the character.
Opposite him, Elizabeth Montgomery, star of the classic sitcom Bewitched, plays the barmaid in Devil’s Hole, adding warmth and intrigue to her brief but important role. Meanwhile, The Omen‘s David Warner reprises his role as Ra’s al Ghul, lending the episode a sense of continuity and gravitas.
The combination of these performers elevates “Showdown” into something special. It’s less about Batman himself and more about the legacy of Ra’s al Ghul, and the casting reflects that shift in focus. With such a stacked lineup, the episode feels like a prestige drama disguised as an animated Western.
Batman: TAS Season 1, Episode 9 “Be A Clown”
“Be A Clown” is a fascinating Batman: TAS episode not just for its story but for its behind-the-scenes casting history. It features two standout voice actors, Jim Cummings and Tim Curry, whose involvement adds an extra layer of intrigue. This time, Cummings voices Jekko, a clown who is kidnapped and impersonated as part of one of Joker’s schemes.
