Why "Lie to me" is translated as "别对我说谎"? The movie name Lie to me, should be directly translated to 对我说谎. But the Chinese translation is 别对我说谎, which is opposite to the expected translation.

Is this common? When should we opposite the meaning when translating English to Chinese?
"Lie to Me" sounds like a challenge (feel free to lie to me and I will see through you).

"别对我说谎" sounds like a warning (Never lie to me or I will see through you).

They are not that contrary but actually quite close in this particular context,  since both convey the subtext "I will see through you".

In Chinese, "对我说谎" isn't as strong as "Lie to me" in English, unless you say "来，对我说谎" or "对我说谎试试" to stress that it's an imperative sentence. I guess this is why the translator chose 别对我说谎 rather than 对我说谎.
