Fans of a popular movie series said they were constantly being distracted from the sequel film's plot because one of the zombies kept flaunting his surprisingly large penis.
28 Years Later, which came out Friday, is the follow-up to 28 Days Later, a 2002 apocalypse film starring Cillian Murphy.
The premise is that Murphy's character, a bicycle courier, wakes up 28 days after a highly contagious virus was released, causing society in Britain to collapse.
The sequel, starring Aaron Taylor-Johnson and Ralph Fiennes, focused on a small group of survivors of the so-called 'Rage Virus' 28 years after the initial outbreak.
Throughout the 2025 film, the group is repeatedly pursued by the Alpha, the noticeably hung zombie that has caught the attention of people on social media.
The Alpha is presumably the leader of the infected and is bigger, stronger and obviously more well-endowed than his counterparts.
Dr. Kelson, one of the survivors played by Fiennes, calls him Samson, a reference to the biblical hero of the same name known for his extraordinary strength and his battles against the Philistines.
The Alpha certainly lives up to his name, as he is able to withstand barrages of arrows and pull off the heads of humans with their spines still attached.
But the Alpha's power in that department was largely ignored by social media users, nearly all of whom were thoroughly focused on his downstairs anatomy.
Many threw around the joke that the film should have been called 28 Inches Later.
One commenter pointed out that the constant full frontal male nudity was only possible because the zombies were wearing no clothes.
According to the movie's logic, they were nude because the clothes they had been wearing had degraded in the decades since they were infected.
'The infected in 28 years later don't wear clothes and it's one infected who got like a 10 incher,' they wrote.
Another person compared the Alpha to Jason Momoa in looks, though the famous actor wasn't actually in the movie.
'Went to 28 years later. Wasn't expecting to see a well hung Jason Momoa zombie throughout the whole thing lmao,' they wrote.
Someone else began to write what seemed like a legitimate review of the movie, only to mention the penis once more.
'28 Years Later is a hauntingly beautiful, deeply affecting evolution of the franchise. There's horror and dread, but also strangely stunning moments of beauty and a giant zombie dong. Well worth the wait,' the person wrote.
Director Danny Boyle has admitted that it was a 'nightmare' filming naked zombies for 28 Years Later (pictured at the movie's World premiere this month)
Behind the scenes, it was a nightmare to film the movie, said Director Danny Boyle.
That's because with all the extras playing nude zombies, the film crew needed to take extra care to protect the film's child star, Alfie Williams.
Boyle told PEOPLE: 'I mean, if you're recently infected [with the zombie virus], you'd have some clothes, but if you've been infected for a long time, the clothes would just disintegrate with the way that you behave.'
'We never knew [about rules governing nudity on set when there's a child present] going in, it was a nightmare.'
In order to still film scenes featuring naked zombies while adhering to the safeguarding rules, Boyle revealed the actors had to wear prosthetics.
'Interestingly, because there was a 12-year-old boy on set, you’re not allowed for anybody to be naked, not really naked, so they look naked, but it’s all prosthetics,' he shared.
'So it’s like: ''Oh my God,'' so we had to make everybody prosthetic genitals.'
Boyle said he was keen to push boundaries with the elements of nudity and gore in the film, and he's glad studio bosses were supportive of his plans.
So far, 28 Years Later has been well received, with an 89 percent score on Rotten Tomatoes.
