Fact check: Bill Skarsgård recreates his Pennywise Smile

Checked on October 30, 2025

Executive Summary

Bill Skarsgård has returned as Pennywise in HBO’s It: Welcome to Derry, and multiple contemporary interviews and set reports describe both the actor’s deliberate preservation of the character’s shock tactics on set and his ability to produce the character’s unsettling grin without relying solely on makeup. Reporting from cast and creators emphasizes that Skarsgård’s physical performance — including the signature Pennywise smile — remains central to the production’s impact, while ancillary coverage and cosplay recreations show the smile’s continued cultural resonance and replication by fans [1] [2] [3] [4].

1. Why the claim matters: Skarsgård’s smile as a production linchpin, not a throwaway prop

Multiple interviews around the series’ launch present the idea that Bill Skarsgård’s Pennywise smile is a deliberate, actor-driven tool used to generate fear and authentic reactions. Creators Andy and Barbara Muschietti framed Skarsgård’s return as essential to the project, stating there was “no Plan B” if he declined, which signals the production’s reliance on his specific interpretation rather than interchangeable effects [2]. On-set accounts add that the young cast were kept unaware of Pennywise’s presence to heighten their responses, a technique that depends on the actor’s capacity to deliver visceral expressions like that smile in situ [1]. Those sources together support the conclusion that any recreation of the smile on set was intentional and central to the show’s creative strategy [1] [2].

2. What the primary on-set accounts actually say: hidden entrances and resurrected terror

Detailed reporting from the set clarifies how the team engineered encounters to maximize fear: Skarsgård was kept hidden to elicit uncontrived reactions, and the emphasis was on the actor’s timing and facial work rather than on post-production fixes. Cast testimonials describe being frightened by Skarsgård’s presence in full costume, implying the physical smile was part of an orchestrated scare strategy rather than a staged PR moment [1]. Creator and actor interviews corroborate this, describing a Pennywise retooled as “pretty hardcore” and unlocking new facets of the clown that the show intends to explore. Those contemporaneous production details constitute the strongest support for the statement that Skarsgård “recreates his Pennywise smile” as a purposeful, on-set performance choice [1] [3].

3. Alternative explanations and fan-driven recreations: cosplay and viral echoes

Beyond production reporting, fan culture and later entertainment pieces show the smile’s diffusion into popular practice. A notable cosplayer recreated Pennywise’s sewer-scene smile and mannerisms, demonstrating that the grin is replicable and circulates independently of Skarsgård’s live performance [4]. Entertainment commentary likewise highlights that Skarsgård can reproduce the grin effectively even without full makeup, emphasizing his facial control and the smile’s memetic power [5]. These sources introduce a secondary angle: while the actor’s on-set recreation matters for the show’s authenticity, the smile also exists as a widely imitated visual motif that can be reproduced by performers and fans, complicating claims that any single instance is uniquely definitive [4] [5].

4. Consistency with historical portrayals: performance technique over prosthetics

Analyses of Skarsgård’s approach dating back to the original IT films show he built Pennywise through voice, physicality, and facial distortion rather than relying purely on prosthetic work; contemporaneous interviews from the earlier film cycle and later commentary reiterate that his grin is a crafted physical effect originating in acting technique [6] [7]. The recent reporting about the HBO prequel continues that narrative, asserting the actor’s smile remains a core instrument. This continuity bolsters the claim that when media say he “recreates” the grin, they refer to a repeatable, intentional acting choice rooted in established technique rather than a one-off stunt or digital trick [6] [7].

5. Bottom line and caveats: what’s proven and what’s inferred from the coverage

Contemporary sources from the show’s promotion and behind-the-scenes accounts substantiate that Bill Skarsgård performed Pennywise in ways designed to showcase his signature grin and that production choices amplified its effect; therefore the core claim that he “recreates his Pennywise smile” is supported by on-set testimony and interviews [1] [3] [2]. However, fan reproductions and later entertainment pieces show the grin’s broader circulation, meaning that not every instance of the Pennywise smile visible online or in media can be assumed to be Skarsgård himself; some are cosplayers or editorial compilations referencing his performance [4] [5]. The most defensible conclusion is that Skarsgård intentionally revived and used the smile in the HBO production, and that this performance choice continues to drive both professional coverage and popular imitation [1] [2] [4].
