Blockbuster films may be billion-dollar affairs these days, but no matter how big the action and spectacle may get, mistakes are bound to happen. Studios may do their very best to keep those flaws from making the final cut (or erase them entirely in post-production, or re-releases) but luckily for movie buffs, some incredible slip-ups still slip through the cracks.

In our experience, we’ve encountered errors or flaws that either aren’t mentioned enough, or simply defy explanation. The filmmakers may have thought their finished film was devoid of all but the most minor flaws, but the following entries show that fans have an eye for detail even some directors lack.
