Kodi not finding film "Rolls Royce Baby"
With Kodi, not finding this film with file name ROLLS_ROYCE_BABY (1975) or ROLLSROYCE_BABY (1975).
Any idea what could be causing this to fail? What should the filename be for this one? Thank you!

There are 2 possible problems:
1 It is likely that, in your profile, the option Include Adult Items in Search? is marked as No.
This movie you are looking for is Adult.

2 The title you are using in your search is not the title of the film here on TMDb.
Rolls-Royce Baby (1975)
