It's amazing how many times I have watched a movie or television show subtitled in one language whilst stating something completely different from what was intended in the source text. This is actually a much more common problem than you'd think. There are many instances in film and television in which the postproduction duties of subtitling are shoddily taken on resulting in, what may seem in many cases, unintelligible target dialogue. To avoid having this happen to your film or television show, make sure you hire a qualified translation provider to take on your subtitling services needs. You and your audience will be thankful that you did.
