20 Things You Somehow Missed In The Mummy (1999)
18. What Chains?
Desperate to locate the hidden land of Hamunaptra, Evelyn heads to a prison with her brother, Jonathan, after learning one of the inmates, Rick O' Connell, has been there. After a bit of banter (and a punch to Jonathan's face), Evelyn prepares to free Rick so he can help her find the City of the Dead.
It's a memorable scene since it's the first time the three heroes get to interact with each other. But another reason why this encounter stands out is because of a glaring mistake. Throughout the scene, Rick has his hands bound in chains.
When Rick utters the line, "Do it, lady." at the end, the chains mysteriously vanish.
Although the chains (or lack of) can't be seen when Rick whips his arms around his back, it's clear he isn't shackled while being escorted away.
