Mystery-thrillers, like this weekend’s "Inferno," keep us clinging to the edges of our seats for dear life. In fact, we’re so busy being thrilled that any continuity errors, gaffes, or all-out mistakes pretty much go unnoticed.

Luckily for you, we’ve compiled a list of movie mistakes pulled from some of cinema history’s most notable mysteries, like "Memento" and "Vertigo." As usual, all photos come courtesy of MovieMistakes.com.
