When it comes to the subject of "acting," there are no set rules. As the saying goes, one man's Nicolas Cage is another man's Laurence Olivier. Or, at least, that's how the saying would go had I not just conjured it up out of thin air to help make my point. Fact is, actors appeal to movie-goers for all sorts of reasons, and it's not always possible to pin down why you like watching a certain actor on the big screen. Ultimately, though, a good actor should be able to make you do one thing: believe. To claim that an actor was "miscast" in a movie role, then, seems kind of wrong. Because ultimately, there's no right way to judge whether or not somebody did a good job, is there? It might just be that only you thought they were miscast, after all, and who are you? Not that I have anything against you specifically - thanks for reading, by the way - I simply mean, in the wider scheme of things, that's just one opinion. And yet, now and again, the casting process can go so horribly wrong that it's impossible to be diplomatic about it. Like now, for instance. Join us as we take a look at 10 horrific miscastings that couldn't have gone more wrong if the associated filmmakers had raced out into the street at random, grabbed somebody by the arm, and told them to act their heart out for eight weeks or face a firing squad. In fact, that's probably exactly what happened, given that these miscastings were so bad, subjectivity died in the wake of their existence, leaving just one indisputable fact to linger in the air: these choices were freakin' horrendous.
