Ok guys, yesterday was too late and I didn't have time check the information fully before going to sleep.
I disagree with the information on TMDb! So as for Taxi 4 has two different language on FRA and ENG.
If take the information from TMDb then they are incorrect. As shown it's from SimonV for Taxi 4.
If I understood correctly, TMDb takes ID from IMDb, and therefore more correct information, will be on IMDb.
If you check information on IMDb then you will see it:
That original title - "
Taxi 4" he same English and on French "
T4xi".

The same goes for the movie "Wild Things" they too absolutely different: (I don't see any similarities)
Original title - "
Wild Things" he same English and on French "
Sexcrimes"

Conclusion: if you check the informations on IMDb then everything looks correct.
I think many will agree with me!
