With the series winding toward its end, The Boys slipped a high-profile cameo into its penultimate installment that briefly stole the spotlight. Creator Eric Kripke has explained how that unexpected guest came to be: a well-known Hollywood voice actor agreed to play a marine character whose appearance reinforces the season’s darker stakes. The finale itself is slated to premiere in 4DX theaters on May 19 before it becomes available for streaming the following day, and the production has used the closing stretch to layer in surprise moments that reward attentive fans.
The surprise this time is that Samuel L. Jackson supplies the voice for a hammerhead shark named Xander, who returns in the episode titled “The Frenchman, the Female, and the Man Called Mother’s Milk.” Xander first showed up earlier in the season premiere, “Fifteen Inches of Sheer Dynamite,” when he ferried The Deep (played by Chace Crawford) on a hunt for A-Train (Jessie T. Usher). In the penultimate episode the shark’s reappearance is no novelty cameo: it shifts the moral balance of a key scene and underlines the consequences of the characters’ actions.
How the voice cameo was arranged
The path to landing Jackson’s voice began with relationships the producers already had in place. Kripke credits executive producers Seth Rogen and Evan Goldberg for helping secure many famous faces this season; he often leans on their connections to make calls on behalf of the show. For the shark, however, the approach was more direct: the team identified Jackson as the ideal vocal match and reached out through his representation. After an inquiry to his agent, Jackson — a first choice — accepted the offer, turning what Kripke describes as a hopeful outreach into a “bucket list” moment for the production team.
What Xander does in the story
On screen, Xander performs an important narrative function: he confronts The Deep about the environmental damage caused by the pipeline that devastated marine life, and he warns the supe that the sea will not forgive him. That confrontation reframes a moment in which the Deep could have acted heroically but instead chooses otherwise. The scene demonstrates the series’ commitment to moral consequences: characters who make harmful choices often face direct retribution, and the shark’s blunt warning seals the point and changes how viewers perceive the Deep’s arc.
Character consequences and tone
Kripke has emphasized that the show’s universe tends to be morally consequential, rewarding right choices and punishing wrong ones in ways that echo human instincts about justice. The Deep and other characters like Firecracker repeatedly encounter chances to do better but opt not to, which the series then punishes dramatically. In this case, the voice cameo by Jackson amplifies the consequence: an animal that had once been an inconvenience for the supe becomes an instrument of accountability when the stakes are raised.
Other celebrity moments in season 5
Season 5 has been dense with cameos beyond Jackson’s appearance. The show has included recognizable media personalities and actors — from a real-world interviewer questioning an in-universe vice president to a reunion of figures associated with other projects of Kripke’s — and several executive producers have also appeared on camera. The program previously used high-profile voices in similar ways: for example, Tilda Swinton provided the voice for Ambrosius, the Deep’s cephalopod companion, in season 4. Those creative choices underline a pattern where celebrity participation is used to heighten moments, sometimes for humor and sometimes to deepen the narrative.
Why these cameos matter
Celebrity cameos on The Boys function on multiple levels: they provide buzzworthy surprises that prompt immediate reaction, they let the show make playful industry-savvy jokes, and they can supply tonal contrast when a familiar voice is placed in an unfamiliar context. Jackson voicing a hammerhead — a nod that may remind some viewers of his character’s fate in the shark thriller Deep Blue Sea — adds an extra layer of irony and delight for audience members who catch the reference.
Above all, the cameo serves story more than spectacle. It deepens a character moment for the Deep, underscores environmental fallout as a theme, and highlights Kripke’s approach to casting recognizable voices as narrative tools. Fans watching the closing episodes will likely parse the choice both as a fun surprise and as an integrated piece of storytelling that strengthens the season’s final beats.
The first seven episodes of The Boys season 5 are available to stream now on Prime Video, and the finale event will debut in 4DX theaters on May 19 before moving to the streaming platform the following day. With a small number of episodes left, expect more intentional surprises that blend celebrity cameos with plot consequences as the series concludes.
