10 Final End Credit Movie Mistakes You Never Noticed
6. Michael Myers' Incorrect Age - Halloween (1978)
Half-way through John Carpenter's inimitable horror masterpiece Halloween, Dr. Loomis (Donald Pleasence) says out-loud that Michael Myers was just six years of age when he murdered his teenage sister Judith (Sandy Johnson).
With the bulk of the movie being set 15 years later, basic maths confirms Myers to be 21 years old during his present day killing spree.
But whoever wrote the end credits clearly had other ideas, as Tony Moran, who briefly played the unmasked version of Myers in the film, is billed as playing the character at age 23.
Hilariously this mistake also carried through to the sequel three years later, where Moran appeared via archive footage from the original movie and was once again credited as a 23-year-old Michael.
Why he wasn't just credited as "Unmasked Michael Myers" is anyone's guess, honestly.
