It has been a surprisingly long stretch since a performer from “Saturday Night Live” truly crossed over into full-fledged superstardom.

Pete Davidson came close, fueled by constant tabloid attention, but his transition into film never quite turned him into a box office force. Kate McKinnon has delivered memorable performances in major studio projects like “Barbie” and “A Minecraft Movie,” yet those films were not built around her as a singular star. Shane Gillis, after being fired from the show, went on to fill arenas as a stand-up comic, but that path is hardly a replicable or predictable blueprint for success.

So is this simply bad timing for comedians emerging from one of pop culture’s most famous launchpads? Or does it reflect deeper changes in the entertainment industry, including the fading dominance of big studio comedies and buzz-driven network sitcoms?

The answer isn’t clear, but the career of Marcello Hernández may offer an illuminating case study. Thanks largely to the popularity of his smooth-talking character Domingo, Hernández has become the most visible breakout performer of the current “S.N.L.” cast. His newly released debut stand-up special on Netflix suggests that he brings not only obvious charisma, but also an intense ambition reminiscent of actors who are determined to win at the game of mainstream show business.

Even the title of the special, “American Boy,” signals that intent. It is deliberately plain rather than clever, leaning into familiarity instead of irony. The word “American,” one of the most overused terms in entertainment titles, carries an easy sense of symbolism and broad appeal. “Boy,” meanwhile, is simple and slightly nostalgic, hinting at one of the special’s most effective emotional tools: a warm, backward-looking affection for childhood.

At 28, Hernández looks and moves like an oversized, hyperactive kid. His hair bounces above wide, animated eyes, and his physical energy feels constantly switched on. When he speaks, his deep, gravelly voice comes as a surprise, clashing in an amusing way with his youthful appearance. His face seems custom-built for exaggeration, whether it’s the pursed lips or the glittering smile. There is something cartoonish about his presence, a playful, Looney Tunes-style quality that makes him immediately likable.

That charm is amplified by a heavy dose of sentimentality. The special opens and closes with Hernández’s mother, a Cuban immigrant who fled the country as a child and raised him and his sister on her own. She introduces him before he takes the stage, greets him with a long hug, and then returns at the end for another embrace. This kind of family involvement has become more common in stand-up, with comedians like Jim Gaffigan, Nate Bargatze, and Leanne Morgan incorporating relatives into their acts.

Here, the emotional framing matters. Much of the material revolves around being raised by a strict, old-school parent, including jokes about corporal punishment delivered without much hesitation. The visible affection between mother and son helps soften these stories, making it clear that Hernández views that discipline as an expression of love rather than resentment.

In fact, the show could almost be retitled “Mama’s Boy.” Hernández describes how, at family gatherings, he was pushed onto the dance floor as a child to entertain relatives, even when he didn’t want to. His mother’s message was blunt: she didn’t escape Cuba for him to stand still. He had to dance.

At one point, Hernández deliberately tightens his smile, making it look just slightly forced. In another comedian’s hands, this could easily become a dark tale about a domineering stage parent and a child pressured to perform through discomfort. But Hernández avoids that tone entirely. He doesn’t linger in bitterness or trauma.

Instead, his comedy mirrors his description of Latin music: upbeat rhythms paired with sad or heavy lyrics. He isn’t a blunt truth-teller or a caustic observer. His childhood memories are filtered through the eyes of a confused, wide-eyed kid trying to make sense of strange adults, including uncles who want to show him a cockroach or offer him a sip of whiskey.

He delivers these stories with a combination of physical enthusiasm and innocent sweetness that recalls classic stand-up moments, like Eddie Murphy describing children reacting to the ice cream truck in “Delirious.” That special famously helped launch Murphy from “S.N.L.” into movie-star territory, and the comparison is hard to ignore.

Hernández also carries himself with a confidence and a light sex appeal that make it easy to imagine him in a romantic comedy. Yet unlike Murphy, he never feels dangerous or rebellious. If anything, Hernández is remarkably obedient. He finds humor in imagining himself reporting other kids to their parents for behavior his own mother would never have allowed.

When he turns to dating, his observations are unusually gentle by the standards of straight male stand-up. He suggests that what women really want is not wealth or status, but attention and listening. In one bit, he describes seeing an attractive woman with an unattractive man. His friend assumes the man must be rich. Hernández disagrees, explaining that the man’s real advantage is something far more powerful: he asks follow-up questions.

As his set progresses, Hernández leans more heavily into accents and exaggerated reactions, echoing the influence of Sebastian Maniscalco, who has become one of the most frequently imitated comics working today. This style works particularly well when Hernández talks about growing up surrounded by women, presenting himself as a serious, battle-hardened reporter delivering grim dispatches from a foreign land.

“They live a violent life behind the scenes,” he says solemnly, before launching into descriptions of Brazilian waxes and first experiences with menstruation. He reenacts his sister casually saying, “Blood only today,” then instantly transforms into his mother, face twisted into a demonic expression, declaring, “Blood forever.”

This stretch is the strongest and funniest part of the special. Hernández’s relentless charm allows him to glide past moments where the joke writing itself may not be especially sharp. Not every bit lands with the same force. A joke about feminist women dancing to songs with sexist lyrics feels like a weaker echo of material Chris Rock explored decades ago. There are also moments where Hernández seems to struggle when his feel-good persona tackles heavier topics, such as the current political rhetoric around immigration.

“I’ve been watching the news for the first time,” he says, slipping back into the forced-smile dancing voice. “Because they’re talking about us.”

The premise starts strong but leads to a somewhat cautious conclusion, suggesting that despite negative headlines, people ultimately love Latino immigrants. As evidence, he points to how warmly white tourists treat Latino workers at resorts. “You love us,” he says. “We’re fun.”

The argument feels underdeveloped, and his usual innocent charm doesn’t fully carry it. The political commentary seems more obligatory than inspired, though it does end on a resonant note. Deportation won’t work, he tells the audience. “We’ll be back,” he says confidently. “We always come back.”

Beneath the bright smile, there is a hint of steel. Hernández is only beginning his career outside “S.N.L.,” and this special feels like an early exploration rather than a final statement. Having seen him perform stand-up in New York, it’s clear that he has other gears, including a sharper, more ruthless ability to chase big laughs when he wants to.

Will he eventually join the ranks of “S.N.L.” alumni like Eddie Murphy, Adam Sandler, or Tina Fey? It’s possible. That level of success depends on timing and luck as much as talent and ambition. What does seem certain is that Marcello Hernández is not done yet. One way or another, he will be back.
