The Chronicles of Narnia: The Lion, the Witch and the Wardrobe (2005) is a beloved fantasy film that introduced audiences to the magical world of Narnia. However, a strange Mandela Effect has emerged regarding the casting of one of its most memorable characters—Mr. Tumnus, the kind-hearted faun who helps Lucy Pevensie when she first arrives in Narnia.
The Memory: Shia LaBeouf as Mr. Tumnus

Many people distinctly remember Transformers star Shia LaBeouf playing the role of Mr. Tumnus. Some claim to recall his recognizable facial expressions and voice, believing he was transformed into the half-goat, half-human character with the help of prosthetics and CGI. This memory is so strong that even those who have rewatched the film are surprised to see someone else in the role.
The Reality: James McAvoy as Mr. Tumnus

In reality, Mr. Tumnus was played by Scottish actor James McAvoy. Known for his performances in Atonement, Split, and as young Professor X in the X-Men franchise, McAvoy delivered a heartfelt and charming performance as the faun who befriends Lucy and ultimately rebels against the White Witch.
Despite this, the mistaken memory persists, leading some to speculate whether people are experiencing a classic case of the Mandela Effect—a phenomenon where a large group of people collectively misremember an event or detail.

Why Do People Remember It Differently?
Here a few possible theories as to why so many associate Shia LaBeouf with the role:
- Time Period Confusion: The Lion, the Witch and the Wardrobe was released in 2005, around the same time Shia LaBeouf was gaining popularity in Even Stevens and Holes, making it plausible for people to associate him with major films of that era.
- Facial Similarities: While McAvoy and LaBeouf do not look identical, some might associate McAvoy’s youthful appearance and expressive acting style with LaBeouf’s performances from that time.
- False Memories from Media Crossovers: LaBeouf was in many popular films of the 2000s, and given that Narnia was widely watched, some viewers may have mistakenly linked the two.
Conclusion
Although many fans are convinced they once saw Shia LaBeouf as Mr. Tumnus, the reality remains that James McAvoy played the role. This Mandela Effect continues to intrigue people, serving as yet another example of how our memories can sometimes deceive us.
